Configuration cannot be loaded. BGPd might experience a crash/core.
'no bgp default ipv4-unicast' statement is used in BGP configuration.
None
Alter the config to get rid of 'no bgp default ipv4-unicast' statement. Without this statement configured neighbors will by default be enabled for IPv4, but they can later be disabled with 'no activate' statement: router bgp 1111 neighbor 10.12.12.12 remote-as 2222 (optionally) no neighbor 10.12.12.12 activate
