Hello!
Okay simple clarification / confirmation
R1 (AS100) <----> R2 (AS200) <---> R3 (AS300)
R1
lo0
3.1.11.0/24
R2
N/A
R3
lo0-13
3.1.1-14.0/24 (Skips 3.1.11.0/24)
R2 Aggregate's the address to a /20 to R1 and R3 however applies an
advertise-map (below
router bgp 200
aggregate-address 3.1.0.0 255.255.240.0 as-set summary-only
advertise-map ADVMAP
!
ip as-path access-list 1 permit ^300
!
route-map ADV permit 10
match as-path 1
To me this means that R2 will send the aggregate to R1 but remove the
AS100 tag from the aggregate? and only show the AS300 and AS200 tag? I
did the reverse to check and it seems right just want any thoughts on
it.
Thanks!
Roger
