Hello,
This task says AS 100's corporate policy dictates it should not provide transit to get to any of AS 54 customers.
r6 is in AS 100 and r2 is in AS 200 with loop0 ip of 150.1.2.2
r6#
router bgp 100
nei 150.1.2.2 remote-as 200
nei 150.1.2.2 filter-list 1 out
!
ip as-path access-list 1 permit _54$
But r2 in AS 200 still shows AS path 100 54 for routes of AS 54
Should'nt it be:
ip as-path access-list 1 deny _54_
ip as-path access-list 1 permit .*
->means match as-path 54 any where in as-path and deny. This way as-path 100 54 will not be matched and AS 100 will not become transit for traffic from AS 200 to AS 54.
The task does not allow use of comminities, IP access-list, or prefix-list.
Any comments....will be appreciated.
