[FROG] Configured AFI/SAFIs do not overlap

[Manuel Schweizer]

Hey Andre

I am not sure whether this will solve your problem, but it always helps me to set up sessions more "explicitly" avoiding MP incompatibilities. That's why I always use `no bgp default ipv4-unicast` in my bgp configs along with explicit `neighbor XXX.XXX.XXX.XXX activate` or `neighbor xxxx:xxxx:xxxx:xxxx::x activate` in the respective address-family sections.

Example:

***

router bgp 397033
no bgp default ipv4-unicast
[...]
!
address-family ipv4 unicast
  neighbor XXX.XXX.XXX.XXX activate
  [...]
exit-address-family
!
address-family ipv6 unicast
  neighbor xxxx:xxxx:xxxx:xxxx::x activate
  [...]
exit-address-family

***

I hope that helps. Please accept my apologies in case I misunderstood.

Cheers,
Manuel
