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
