Re: BGP4 implementation

Hi Elmer !

Just u need to configure the community filtering at RouterA as

RouterA # neighbour  <IP of RTB>  remote-as xxx
RouterA # neighbour  <IP of RTB> send-community
RouterA # neighbour  <IP of RTB> route-map abcd out

route-map abcd 100
 match ip <Access-list number>
 set community no-export


These set of commands will tell the RTB not to export the routes learned frm ur
AS to its other external peers. I hope this will cmet ur configuration. Pls
update me if u find better alternate solution.

Regrds

Subject:  BGP4 implementation




Hi, group.
I need some help on filtering BGP4. The scenario is this: my routerA is set
up
with a T1 to routerB via static classB address. However, RouterB is also
connected to other clouds running BGP4. I do want users in RouterB cloud to
get to my network, but I don't want the other clouds that connect to RouterB
to get into my network. The simple questions are: is it just a matter of
RouterA
using ACL to allow only RouterB? Is it telling the NetAdmin of RouterB to
modify his route-redistribution config so no routes outside of RouterB's
cloud
gets sent to my RouterA? Are there any other issues or configurations I'm
better off implementing? Thanks as always to all kind responses.
