[quagga-users 14354] Re: redistribute both IPv4 and IPv6 connected routes - howto?

Mon, 13 Jun 2016 04:11:10 -0700 

Anil,

it looks like the same issue as seen before.
The problem seems to be the route-map attached to the redistribute connected and 
having 2 different route-maps (one each for IPv4 and IPv6)
Please try the following to verify that this is the same bug as I debugged earlier 
and as a workaround for you:
Create a new route-map with IPv4 _and_ IPv6 in it (yes, sounds weird… but 
Quagga allows this):

        route-map IPFOURANDSIX permit 10
         match ip address 1
        !
        route-map IPFOURANDSIX permit 20
         match ipv6 address IPV6
        !
        route-map IPFOURANDSIX deny 30
        !
and then attach this route-map to BOTH redistribute connected statements: 

        router bgp 65056
         bgp router-id 12x.xxx.xx.235
         aggregate-address 6x.x.x.x/24 summary-only
         redistribute connected route-map IPFOURANDSIX
         neighbor 12x.xxx.xx.227 remote-as 65059
         neighbor 12x.xxx.xx.228 remote-as 65059
         neighbor 2xxx:x:xx:x::a1 remote-as 65059
         no neighbor 2xxx:x:xx:x::a1 activate
         neighbor 2xxx:x:xx:x::a2 remote-as 65059
         no neighbor 2xxx:x:xx:x::a2 activate
        !
         address-family ipv6
         redistribute connected route-map IPFOURANDSIX
         neighbor 2xxx:x:xx:x::a1 activate
         neighbor 2xxx:x:xx:x::a2 activate
         exit-address-family
         exit

Please confirm if this works.
It is still a bug - no question there, but if I’m correct then this should work 
and be useable as a workaround for you.

Anil,

sorry for the long delay…
I just troubleshooted a similar (or same) issue with someone else.
Curious ti find out if this is the same issue.

Can you post the “router bgp …” section of your configuration?
(Incl route-maps and filter/prefix lists)

If you don’t feel like posting the whole BGP config, then either
email it to me privately or replace the IPs with some dummy numbers
and blank out any potential passwords.

Hi Guys,
I've been trying to get both ipv4 and ipv6 routes in place with BGP, found no luck so far, Surfing the internet lead me to the same issue 
reported earlier in ilist
<
https://lists.quagga.net/pipermail/quagga-dev/2011-September/008869.html

.
I've trying this on latest version 1.0.20160315 and find no success. 
 I
also tried 0.99.20 with patch attached to the earlier ilist and that 
works
like charm.
Can someone help how can i achieve this with latest version of quagga?
Below is the test output for both 1.0.20160315 and patched version of 
0.99.20
