Hi Group,
IEWBv2 lab 9 - 6.4 : "configure R6 to only accept prefix from BB1 that
have been originated by themselves and their directly connected
customers."
WB Solution:
R6:
router bgp 100
neighbor 54.2.1.254 filter-list 25 in
!
ip as-path access-list 25 permit ^54(_[0-9]+)?$
I have another solution for regexp:
ip as-path access-list 25 permit ^54_[0-9]*$
Is it totally equivalent to the WB solution, and meet the requirement?
Thanks,
Taylor
