Hi Darth:
Unfortunately, you cannot remove it...because the default bgp config is for
ipv4 only. when you configure #router bgp 1
but if you configure an additional cmd under it: #no bgp default ipv4-unicast
it will not show up. This means that your goal is to only configure bgp for
vpnv4.
Then you activate the vpnv4 neighbor under address-family vpnv4.
Rack2R8(config)#router bgp 1
Rack2R8(config-router)#no bgp default ipv4-unicast
Rack2R8(config-router)#nei 1.2.3.4 remote-as 2
Rack2R8(config-router)#address-family vpnv4
Rack2R8(config-router-af)#nei 1.2.3.4 activate
Rack2R8(config-router-af)#end
Rack2R8#sh run | b router bgp
router bgp 1
no bgp default ipv4-unicast
bgp log-neighbor-changes
neighbor 1.2.3.4 remote-as 2
!
address-family vpnv4
neighbor 1.2.3.4 activate
neighbor 1.2.3.4 send-community extended
exit-address-family
The IOS is "quirky". For ex. if you then decide to also configure ipv4
neighbors and you did a #bgp default ipv4-unicast, then you will see the ipv4
neighbor but it will not be activated because once again, it's default
behavior. You will have to activate it manually. Play with it and see for your
self...it is how the IOS behaves.
Rack2R8(config)#router bgp 1
Rack2R8(config-router)#bgp default ipv4-unicast
Rack2R8(config-router)#end
Rack2R8#sh run | b router bgp
router bgp 1
bgp log-neighbor-changes
neighbor 1.2.3.4 remote-as 2
!
address-family ipv4
no neighbor 1.2.3.4 activate
no auto-summary
no synchronization
exit-address-family
!
address-family vpnv4
neighbor 1.2.3.4 activate
neighbor 1.2.3.4 send-community extended
exit-address-family
Then you would go under ipv4 and activate the neighbor.
Good Luck.
