Support.

This is an important draft and is implemented;

​

  1.  ​I echo Acee's comment re: "Router MAC" for readability



AS> I also echo my reply to Acee’s comment ☺



(2) The document often refers to two Route-targets (MAC-VRF & IP-VRF) which is 
overly restrictive.

I would propose language more to the effect of MAC/IP must be advertised with 
two sets of RTs



AS> “two Route targets” are used when the document talks about Route-Type-2 – 
which is in context of a single EVI for MAC-VRF and IP-VRF.



Cheers,

Ali



RFC7432:  EVPN route MAY carry one or more Route Target (RT) attributes.​

vs. for example:

   This route MUST be advertised with two route targets - one

   corresponding to the MAC-VRF of the tenant's subnet and another

   corresponding to the tenant's IP-VRF.

Hi Stephane, Authors,

I support advancement. This is a useful optimization that has been implemented .

Two comments:


  1.  Call the new BGP Community “Router MAC” rather than “Router’s MAC”.

AS>  It is already registered with IANA as “Router’s MAC”, so I am reluctant to 
change it at this point. However, if RFC editor make the same complain, then I 
will change it then.


  1.   Consistently use “TSes” to refer to multiple Tenant Systems and “TS’s” 
to refer to an address or other entity processed by a Tenant System.

AS> OK. Done.

Cheers,
Ali

I have some other editorial comments that I will pass to the authors.

Cc: "stephane.litkow...@orange.com" 
Subject: Re: [bess] new WGLC for draft-ietf-bess-evpn-inter-subnet-forwarding-05

Hello working group,


I have two comments regarding section 3.1.


* Section 3.1. refers only to “ARP” or “ARP reply”. Given the fact, it is 
applicable to IPv6 as well, it should refer to ND NS/NA messages as well, I 
believe.

OK. Added ND NS along with ARP request  and ND NA along with ARP reply.


* In the last paragraph of Section 3.1:


>  Irrespective of using only the anycast address or both anycast and

   non-anycast addresses on the same IRB, when a TS sends an ARP request

   to the PE that is attached to, the ARP request is sent for the

   anycast IP address of the IRB interface associated with the TS's

   subnet.
If both anycast and non-anycast addresses are on the IRB, it is legitimate that 
TS sends NS/ARP request to resolve either anycast (e.g. to resolve IP address 
of default gateway configured on TS), or to resolve non-anycast (e.g. ping 
towards non-anycast address was initiated on TS). Therefore, presuming that TS 
sends ARP request to resolve only anycast IP is not fully correct, I believe. 
Thus, wording of this paragraph should cover two cases (NS/ARP request to 
resolve anycast, and NS/ARP request to resolve non-anycast IP).

TS is not supposed to use non-anycast addresses on the IRB interface because if 
OAM pinging is needed by the TS to the IRB interface, it can do that using 
anycast address. Non-anycast addresses are intended to be used by network 
operator for its OAM within the EVPN network.


>> the PE1 sends an ARP reply with the MACx which is the anycast

   MAC address of that IRB interface.
NA/ARP reply has multiple MAC related fields:

* Destination MAC (in Ethernet header)
* Source MAC (in Ethernet header)
* Sender hardware address (in the payload)
* Target hardware address (in the payload)

It is not ultimately clear from the text, if 'Source MAC (in Ethernet header)’ 
or 'Sender hardware address (in the payload)’, or both, should be populated 
with MACx. As I see it, in case of both anycast and non-anycast address is used 
on IRB, the behavior should be:

Since we are talking about only anycast addresses to be used by the TS, then it 
should be clear that only anycast MAC address will be used  - i.e., in both 
source MAC (in Ethernet header) and Sender hardware address (in the payload). 
However to make that crystal clear, I modified the 1st half of the last para as 
follow:
“Irrespective of using only the anycast address or both anycast and non-anycast 
addresses on the same IRB, when a TS sends an ARP request or ND Neighbor 
Solicitation (NS) to the PE that is attached to, the request is sent for the 
anycast IP address of the IRB interface associated with the TS's subnet and the 
reply will use anycast MAC address (in both Source MAC in the Ethernet header 
and Sender hardware address in the payload).”

Cheers,
Ali

* TS sends and NS/ARP request for the anycast address:
   -> PE sends and NA/ARP reply with anycast MAC in both 'Source MAC (in 
Ethernet header)’ and 'Sender hardware address (in the payload)’ fields

* TS sends and NS/ARP request for the non-anycast address:
   -> PE sends and NA/ARP reply with non-anycast MAC in both 'Source MAC (in 
Ethernet header)’ and 'Sender hardware address (in the payload)’ fields

Otherwise, if only 'Sender hardware address (in the payload)’ is populated with 
anycast/non-anycast MAC (depending, which IP address is being resolved), and 
'Source MAC (in Ethernet header)’  is always populated with no-anycast MAC (in 
implementations mimicking RFC 5798, Section 8.1.2/8.2.2/8.2.3 behavior, which 
explicitly disables usage of V-MAC in the 'Source MAC (in Ethernet header)’), 
the L2 domain (L2 switches) between PE and CE will not learn anycast MAC, thus 
resulting in unknown unicast flooding being used on these switches to reach 
anycast MAC. This is undesirable behavior and should be avoided.


Thanks,
Krzysztof

This is an important draft and is implemented;


​


​(1) I echo Acee's comment re: "Router MAC" for readability





(2) The document often refers to two Route-targets (MAC-VRF & IP-VRF) which is 
overly restrictive.


I would propose language more to the effect of MAC/IP must be advertised with 
two sets of RTs




RFC7432:  EVPN route MAY carry one or more Route Target (RT) attributes.​

vs. for example:

   This route MUST be advertised with two route targets - one
   corresponding to the MAC-VRF of the tenant's subnet and another
   corresponding to the tenant's IP-VRF.


Thanks,

Luc André​ Burdet

[Acee Lindem (acee)]

Hi Stephane, Authors,

I support advancement. This is a useful optimization that has been implemented .

Two comments:


  1.  Call the new BGP Community “Router MAC” rather than “Router’s MAC”.
  2.   Consistently use “TSes” to refer to multiple Tenant Systems and “TS’s” 
to refer to an address or other entity processed by a Tenant System.

I have some other editorial comments that I will pass to the authors.

Thanks,
Acee

Re: [bess] new WGLC for draft-ietf-bess-evpn-inter-subnet-forwarding-05

[Krzysztof Szarkowicz]

Hello working group,


I have two comments regarding section 3.1.


* Section 3.1. refers only to “ARP” or “ARP reply”. Given the fact, it is 
applicable to IPv6 as well, it should refer to ND NS/NA messages as well, I 
believe.


* In the last paragraph of Section 3.1:

>  Irrespective of using only the anycast address or both anycast and
   non-anycast addresses on the same IRB, when a TS sends an ARP request
   to the PE that is attached to, the ARP request is sent for the
   anycast IP address of the IRB interface associated with the TS's
   subnet.
If both anycast and non-anycast addresses are on the IRB, it is legitimate that 
TS sends NS/ARP request to resolve either anycast (e.g. to resolve IP address 
of default gateway configured on TS), or to resolve non-anycast (e.g. ping 
towards non-anycast address was initiated on TS). Therefore, presuming that TS 
sends ARP request to resolve only anycast IP is not fully correct, I believe. 
Thus, wording of this paragraph should cover two cases (NS/ARP request to 
resolve anycast, and NS/ARP request to resolve non-anycast IP).

>> the PE1 sends an ARP reply with the MACx which is the anycast
   MAC address of that IRB interface.
NA/ARP reply has multiple MAC related fields:

* Destination MAC (in Ethernet header)
* Source MAC (in Ethernet header)
* Sender hardware address (in the payload)
* Target hardware address (in the payload)

It is not ultimately clear from the text, if 'Source MAC (in Ethernet header)’ 
or 'Sender hardware address (in the payload)’, or both, should be populated 
with MACx. As I see it, in case of both anycast and non-anycast address is used 
on IRB, the behavior should be:

* TS sends and NS/ARP request for the anycast address:
   -> PE sends and NA/ARP reply with anycast MAC in both 'Source MAC (in 
Ethernet header)’ and 'Sender hardware address (in the payload)’ fields

* TS sends and NS/ARP request for the non-anycast address:
   -> PE sends and NA/ARP reply with non-anycast MAC in both 'Source MAC (in 
Ethernet header)’ and 'Sender hardware address (in the payload)’ fields

Otherwise, if only 'Sender hardware address (in the payload)’ is populated with 
anycast/non-anycast MAC (depending, which IP address is being resolved), and 
'Source MAC (in Ethernet header)’  is always populated with no-anycast MAC (in 
implementations mimicking RFC 5798, Section 8.1.2/8.2.2/8.2.3 behavior, which 
explicitly disables usage of V-MAC in the 'Source MAC (in Ethernet header)’), 
the L2 domain (L2 switches) between PE and CE will not learn anycast MAC, thus 
resulting in unknown unicast flooding being used on these switches to reach 
anycast MAC. This is undesirable behavior and should be avoided. 


Thanks,
Krzysztof
