MPLS VPN Peer-Group

Hi All,

          I will be most grateful if anyone could please clarify if the below config makes the MYP an IPv4 peer-group member of a VPNV4 peer-group memeber?.

router bgp 1

no synchronization

neighbor MYP peer-group

neighbor MYP remote-as 1

neighbor MYP update-source Loopback0

neighbor 10.0.0.2 peer-group MYP

no auto-summary

!

address-family ipv4 vrf VPN1

redistribute ospf 10

no auto-summary

no synchronization

exit-address-family

!

address-family vpnv4

neighbor MYP activate

neighbor MYP send-community extended

neighbor 10.0.0.2 peer-group MYP

no auto-summary

exit-address-family

My point of confusion was, why was the peer-group configuration deployed under the routing process (IPv4) and at the same time under the VPNV4 configs?. Is this practical?.

Any assistance with clear explanation shall be greatly appreciated,

Olu

Olu,

Can you perhaps be more specific in what is your question? I am not sure I fully understand what you are asking about.

In any case, on my 2691 12.4T IOS, I was not able to enter the neighbor MYP activate in the address-family vpnv4 section - the command was refused with the comment

% Peergroups are automatically activated when parameters are configured

The neighbors appear to require individual activation for address families. Instead, I had to activate the neighbor 10.0.0.2 in the appropriate address family. Your configuration as displayed was not identical to what I had in my configuration - after putting in your configuration, this was the result:

router bgp 1

no synchronization

bgp log-neighbor-changes

neighbor MYP peer-group

neighbor MYP remote-as 1

neighbor MYP update-source Loopback0

neighbor 10.0.0.2 peer-group MYP

no auto-summary

!

address-family vpnv4

  neighbor MYP send-community extended

  neighbor 10.0.0.2 activate

exit-address-family

!

address-family ipv4 vrf VPN1

  redistribute ospf 10 vrf VPN1

  no synchronization

exit-address-family

Best regards,

Peter
