deny specific prefixes in bgp

[Elie_Raad]

Hi,
i am trying to deny exact prefixes 66.133.0.0/23 and 66.133.2.0/23 from being advertised and allow everyhting else to an iBGP neighbor (214.63.21.4) the configuration should be done on 214.63.21.3. using a neighbor route-policy command.

Neighbor 214.63.21.3 is connected to neighbor 214.63.21.4.

can someone help .
thank you,
elie

Hi Elie,

There is an implicit deny on routing policies, so you would need an explicit permit all entry to allow other prefixes.

Hi Brandon,
all other routes other than 66.133.0.0 66.133.2.0 will be allowed correct ? or everything else will be blocked too ?
