But
If i config a static-routing on R1,(ip route 3.3.3.3 255.255.255.255 2.2.2.2),
The EBGP-Session is established !!! (It's trivial !!)
=> Why don't the local-policy route-map configuration oprate well ??
Who know the reason ????
-------------------------------
Thanks for your reply..
But in the Assumtion..
R3 has a D/R to the R1's E0(2.2.2.1)
so, R3 has a route to the R1's L0(1.1.1.1) with a source ip 3.3.3.3
=> If R3 sends a ping to the R1's Lo(1.1.1.1) with a source R3's Lo(3.3.3.3),
it's OK!!!
Further more, even if i config the local-policy route-map in R3 as you
suggested, the ebgp-session is not established..yet..
How can i fix this problom !!!!
