VRF lite troubleshooting

teymur azimov · ‎10-28-2013

Hi Dears,

I attache my network topology and configuration here. i configurate vrf lite in cisco 6500 series switch. router and asa connected to cisco 6500 switch.

i want to do ping from router to asa inside subnet and also ping from asa to router inside subnet. i configurate eigrp dynamic routing in router and asa,coresw.

the problem is. Ping is not going from router to asa inside network and same thing in asa. is this problem in import/export? May i change some config in my configuration?

configuration in core switch:

ip vrf asa

rd 65515:1

route-target export 65515:1

route-target import 65515:100

route-target import 65515:101

ip vrf mapas

rd 65515:100

route-target export 65515:100

route-target import 65515:101

route-target import 65515:1

!

ip vrf mapas1

rd 65515:101

route-target export 65515:101

route-target import 65515:100

route-target import 65515:1
