ipv6 connectivity bugs

[Mike]

Hello,

I have a 7201 and an ASR1000 and they share a link and run ipv4 and 
bgp over it no problem.


I am experimenting and have now added some static ipv6 
configuration, and I can't seem to ping across the link. The issue looks 
like one side us advertising prefixes correctly and the other isn't. 
Here's my interface configs:



ASR1000:

interface TenGigabitEthernet0/1/0.110025
  encapsulation dot1Q 25 second-dot1q 11
 ip address x.x.x.1 255.255.255.248
 ipv6 address :::1:1/126
end

7201:

interface GigabitEthernet0/0.110025
  encapsulation dot1Q 25 second-dot1q 11
 ip address x.x.x.2 255.255.255.248
 ipv6 address :::1:2/126
end

When I try pinging 7201 from the asr1000, no response. I do see a 
neighbor entry on the asr1000:


sh ipv6 neighbors
IPv6 Address  Age Link-layer Addr State 
Interface
:::1:2  0 ..8e1b  REACH 
Te0/1/0.110025
FE80::::FE49:8E1B   0 ..8e1b  REACH 
Te0/1/0.110025



On the 7201 however, there seems to only be the link local address 
neighbor entry for the asr1000:


sh ipv6 neighbors
IPv6 Address  Age Link-layer Addr State 
Interface
FE80::::FE2D:D190   0 ..d190  STALE 
Gi0/0.110025



Can anyone spot what I am doing wrong?

Just a shot in the dark, are you able to run port-mode EoMPLS on the
ME3600X side as well?

Mark.

Re: ipv6 connectivity bugs

[Dave Bell]

Do you have anything in the way of COPP on either box that may be
dropping packets? I would imagine the issue is likely to be on the
AS1k end.

Additionally I see you have different interface speeds at each side.
Is the thing in the middle at fault? ND is done using multicast.

One final thing is attempt to ping across the link local addresses.
Make you you set the source address correctly.

Dave

I am able to ping the link local address of the 'opposite end' from each 
side, so it looks so me like that is working. I also notice, when I try 
pinging the 7201 from the asr1000, during that time, the output of 'show 
ipv6 neighbors" shows me this:


sh ipv6 neighbors
IPv6 Address  Age Link-layer Addr State 
Interface
FE80::::FE2D:D190   6 ..d190  STALE 
Gi0/0.110025
:::1:1  0 -   INCMP 
Gi0/0.110025


It looks to me like enough is 'working' that the asr1000 -> c7201 
path is working, but not the other way around. And no, far as I know, I 
have no copp or other filtering that would (to my knowledge) create a 
one way situation. As far as the middle, I have ip/mpls that is bridging 
my vlan25 across the network:



! ME3600x - Facing ASR1000
Interface TenGigabitEthernet0/1
switchport trunk allowed vlan none
 switchport mode trunk
 mtu 9216
 service instance 25 ethernet
  encapsulation dot1q 25
  rewrite ingress tag pop 1
  xconnect 10.0.15.3 2 encapsulation mpls
   mtu 9216
!


! ME3600 - facing c7201
interface Vlan25
 mtu 9216
 no ip address
 xconnect 10.0.15.2 2 encapsulation mpls
!


Do I need to make a special provision somewhere for multicast? This 
seems pretty basic setup to me.

IMIX or similiar near-user-load packet generator

Hi all.
Is there any opensource packet generator which can simulate a load
closest to real users? Usually I use iperf, but it can simply generate
huge load.

Does anyone have any suggestions on equipment for our ISP that is still
supporting dial up customers?

At the moment we are running 3Com Total Control 1000's but are running out
of spare parts as we have failures.  Given that this gear is so old trying
to source spare parts is proving to be difficult.

We do have access to an Cisco AS5200 but are looking for maybe a SIP based
solution that could possibly run on our VM farm?  Has anyone heard of
anything like that or does it even exist?

What kind of gear are you running if you still are supporting dial up
customers?

Static IPs

[Joel Maslak]

A helpful hint from a local broadband provider (I'm trying to wade through
broadband options at home):

"If your business is online, then you should have an IP address."

I do find that helps.

(in fairness, they are talking about static IPs, but it kind of fits with
the rest of their marketing which says their highest speed plans include
the advantage of "most reliable Wifi" when compared to their lower speed
plans)

This reminds me of the marketing strategy back when I worked for a
dialup ISP. We originally sold a 240 hour dynamic dialup account and a
24/7 dialup account. Once we got a couple of good salesman, they
pointed out a problem to us: all our competitors claimed they were
selling "unlimited" dialup. Our 240 hour plan wasn't competitive with
"unlimited" dialup even though few users consumed more than 100 hours.

The owner agreed that the basic dialup was not unlimited. He also
agreed that we had to be competitive with other ISP's unlimited dialup
plans. But, rarely among owners, he agreed that it would not be honest
to call a capped dialup plan unlimited.

The solution: "unlimited attended dialup." How would we have any idea
whether the customer was sitting in front of his computer? In general,
we wouldn't. But if he was online 72 hours straight, we had a pretty
solid assumption that he wasn't there the whole time.

The salesmen had their word "unlimited" without lying or abandoning
the usage cap.

Re: sfp "computer"?

[Chip Marshall]

I don't know if they're pushing it for the QFX5100, but I think
on the QFX10k line they're pushing the ability to run another
guest VM alongside the 2 JUNOS VMs on the switch's x86 CPU.

See page 4 on the spec sheet:
http://www.juniper.net/assets/us/en/local/pdf/datasheets/1000531-en.pdf 

No idea what's involved with packaging the VM and getting it there, but
should open up some interesting possibilties.

Well, the switch facing the 7201 is also an ME3600X. Meaning that you
can use EVC Xconnect on there like you did on the one facing the ASR9001.

EoMPLS on an EFP is the same as port-mode EoMPLS. So where you have the
BD for VLAN 25, consider running EoMPLS directly on that EFP instead of
on the SVI.
