Sat Jul 13, 2019 6:39 pm

Hello,
For blackhole a /32 we add that /32 in bgp->networks then in our bgp filtering rules accept it with the community that our upstream give us, but i am curious whats the difference between this action with add that /32 with bgp-community and blackholing type in routing table, are both of them same and discard traffic towards my uplink and sent an update to my bgp peers with that community ?
Thank you.
