Implicit vs Explicit Withdraw in BGP

[eddie.lindsay]

Hello,

On a show ip bgp nei command there is a block of output headed "Prefix Activity" and in there are stats for both "Implicit Withdraw" and "Explicit Withdraw".

Does anyone know what the difference is. I've had a look around on CCO but can't find any detail.

Thanks

"Implicit withdraw" means the prefix is implicitly withdrawn by sending the same prefix with new attributes.

"Explicit withdraw" means sending an actual withdraw message for a given prefix.

Hope this helps,

it does.

Thanks for the reply.
