"nat из global в vrf"
Отправлено OVDP , 17-Сен-09 07:57

Приветствую уважаемые!
подскажите как можно решить следующую задачку:
необходимо выделить пользователю в VRF как бы белый айпи, для того что бы до него достучаться из DMZ или OUTSIDE (тырнет)
соорудил в лабе следующий конфиг (c7200-advipservicesk9-mz.122-33.SRC2):
ip subnet-zero
ip vrf EDGE1
rd 200:100
!
ip cef
!
interface GigabitEthernet2/0
description DMZ1
ip address 192.168.12.30 255.255.255.0
ip nat inside
negotiation auto
!
interface GigabitEthernet3/0
description INSIDE1
ip vrf receive EDGE1
ip address 192.168.13.30 255.255.255.0
ip nat inside
ip policy route-map INSIDE1
negotiation auto
!
interface GigabitEthernet4/0

ip vrf forwarding EDGE1
ip address 10.0.0.1 255.255.255.0
ip nat outside

нашел в чем грабля, может кому нить будет полезно:
строку ip nat outside source static 10.0.0.2 192.168.255.254 vrf EDGE1
заменил на ip nat outside source static 10.0.0.2 192.168.255.254
