Re: [pmacct-discussion] Unable to specify "bgp_ip=::1" in bgp_agent_map

[Charlie Smurthwaite]

Thank you very much Paolo!

The parser now accepts this configuration, but it still doesn't quite 
work. Here is  my bgp_agent_map now:


bgp_ip=127.0.0.1   ip=0.0.0.0/0 filter='ip  or (vlan and ip)'
bgp_ip=::1 ip=0.0.0.0/0 filter='ip6 or (vlan and ip6)'

It seems that while ::1 is now accepted, it doesn't actually match the 
peer. Here is the BGP log output:


INFO ( default/core/BGP ): maximum BGP peers allowed: 2
INFO ( default/core/BGP ): waiting for BGP data on :::17917
INFO ( default/core/BGP ): [127.0.0.1] BGP peers usage: 1/2

INFO ( default/core/BGP ): [185.5.34.12] BGP_OPEN: Local AS: 65535 
Remote AS: 65535 HoldTime: 240


If i bring up only the IPv6 peering, the following (using the router ID) 
works and resolves only IPv6 ASNs. Unfortunately, both my IPv4 and IPv6 
sessions use the same router ID.


bgp_ip=185.5.34.12  ip=0.0.0.0/0

It seems that something isn't quite right with matching "bgp_id=::1" 
against the session originating from ::1. Would you mind seeing if you 
can reproduce this?


Thanks!

Charlie

Hi,

I am running pmacctd with 2 BGP sessions to a local bird instance, one
for IPv4 and one for IPv6. I have written a bgp_agent_map a follows:

bgp_ip=127.0.0.1 ip=0.0.0.0/0 filter='ip'
bgp_ip=::1   ip=0.0.0.0/0 filter='ip6'

Unfortunately, the second line fails to parse. The error is:

WARN ( default/core ): [/etc/pmacct/bgp_agent_map:2] required key
missing. Required keys are: 'id', 'ip'. Line ignored.

I have tried various other IPv6 addresses in place of "::1" and they
work, but "::1" and "0:0:0:0:0:0:0:1" will not work. I have tested this
on 1.6.1 and master. Is this a bug?

Thanks!
Charlie
