Hi all,
I notice below description in user guide, my understand is source address
mainly used for BGP session for TCP connection ,don't understand why this
source is also used as next_hop_addr calculation. If source address is related
with next hop calculation, this case is may not support: used MP_REACH_NLRI to
support IPV4 route with IPV4 next hop ,but TCP connection type is IPV6. Since
to support MP_REACH_NLRI for ipv4 channel, need to enabled ext_next_hop, if
enabled ext_next_hop, if ipv6 source address is selected as next_hop_addr if
no others configuration for next_hop_addr. Does my understand is correct ?
source address ip
Define local address we should use for next hop calculation and as a source
address for the BGP session. Default: the address of the local end of the
interface our neighbor is connected to.
Thanks
Arvin
