Hi Gents,
My question is with reference to Task 6.5/6.6in IEWB Vol I, Lab 3.
The tasks, in brief, ask us to ensure AS 100 doesn't allow a transit for traffic fromAS 300 and AS 200 towards
AS 54. The configuraiton should be done only on R6 in AS 100.
AS 200 (R5) --------- ------ (R1) ------- AS 54 (BB1)
-------- AS 100 (R6)-------
AS 300 (R2)---------- ------ (R3) ------- AS 54 (BB3)
IEWB Solution Guide Suggests to using COMMUNITY (inbound) on the neighbor statement towards the two AS 54 EBGP Peers (BB1 and BB3).
If I choose to use 'ip as-path access-list 10 permit ^$ ' using route-maps on to those BB routers , do you think that will be a correct solution - AS 100 will forward only the local-AS routes to AS54 and will not become a transit
Appreciate your valuable comments please.
Thanks,
manoj
