I'm using quagga 0.99.20-r1 from Gentoo portage.
I have configuration with 2 bgp views:
router bgp 35714 view Infoservice
bgp router-id 184.108.40.206
[about 10 peers skipped]
neighbor 220.127.116.11 remote-as 35714
neighbor 18.104.22.168 description RS Triangle
neighbor 22.214.171.124 update-source 126.96.36.199
neighbor 188.8.131.52 soft-reconfiguration inbound
neighbor 184.108.40.206 prefix-list q3pl-Triangle in
neighbor 220.127.116.11 route-map map-local-preference-Triangle in
neighbor 18.104.22.168 route-map map-IS-Triangle out
router bgp 35714 view Triangle
bgp router-id 22.214.171.124
neighbor 126.96.36.199 remote-as 35714
neighbor 188.8.131.52 description RS Infoservice
neighbor 184.108.40.206 update-source 220.127.116.11
neighbor 18.104.22.168 soft-reconfiguration inbound
neighbor 22.214.171.124 prefix-list q3pl-Infoservice in
[some peers skipped]
Both addresses - 126.96.36.199/25 and 188.8.131.52/25 - are exists on
the same vlan.
1st view (Infoservice) collects announces from different peers and
sends resulting routing table on the border switch.
2nd view (Triangle) share announces between some peers, build own
routing table (from all peers) and announce resulting table to 1st
This scheme works fine.
But there is one problem.
When I begun some experiments with configuration - deleting peer
184.108.40.206 from view Triangle and try to create _with the same
configuration_ - I got error message:
Can not configure the local system as neighbor
I understand the sence of this error - quagga don't allow me to
configure different peers on the same server. But I don't understand
- why? The above scheme works fine without errors. So why I can't
use this scheme?
I was need to delete vlan with 220.127.116.11/25 and 18.104.22.168/25,
restore configuration, and than recreate deleted vlan.
I compile last quagga (0.99.21) from sources on different server to
make patch to turn off check for peers on same interface. But I
can't reproduce error. Views and peers were created without errors.
But check still present in code.
So I have some asks:
1. To developers: please, add option in 'configure' to exclude from
code check for several peers on th same interface.
2. To all: please, help me to reproduce error message.
