On a C1101-4P two VRFs "ABC" and "DEF" and internet access on G0/0/0.
I'd like to NAT overload both VRFs (VLAN interfaces) to G0/0/0.
Here's the relevant config:
vlan 10 name ABC ! vlan 20 name DEF vrf definition ABC rd 10:10 ! address-family ipv4 route-target export 10:10 route-target import 10:10 exit-address-family vrf definition DEF rd 20:20 ! address-family ipv4 route-target export 20:20 route-target import 20:20 exit-address-family interface GigabitEthernet0/0/0 description #W UPLINK-TO-INET ip address 188.8.131.52 255.255.255.248 ip nat outside media-type rj45 negotiation auto interface Vlan10 description #C ABC vrf forwarding ABC ip address 192.168.9.254 255.255.255.0 ip nat inside standby version 2 standby 10 ip 192.168.9.1 standby 10 priority 110 standby 10 preempt standby 10 name ABC interface Vlan20 description #C DEF vrf forwarding DEF ip address 172.16.0.254 255.255.255.0 ip nat inside standby version 2 standby 20 ip 172.16.0.1 standby 20 priority 90 standby 20 preempt standby 20 name DEF ip nat inside source list ABC interface GigabitEthernet0/0/0 vrf ABC overload ip nat inside source list DEF interface GigabitEthernet0/0/0 vrf DEF overload ip route 0.0.0.0 0.0.0.0 GigabitEthernet0/0/0 184.108.40.206 name #DEFAULT-TO-INET ip route vrf ABC 0.0.0.0 0.0.0.0 220.127.116.11 global name #DEFAULT-TO-INET-VRF-ABC ip route vrf DEF 0.0.0.0 0.0.0.0 18.104.22.168 global name #DEFAULT-TO-INET-VRF-DEF
For testing purposes I have a Loopback Lo0 with IP 22.214.171.124/32 in Global routing table. Also, HSRP is not in use (second device not active).
I'm able to reach the IP's 192.168.9.254 and 192.168.9.1 from my client. But never the IP 126.96.36.199 or the INET interface.
Software version is: 17.03.04a (also tried with 16.12.05)
Can someone guide me in the right direction?
Solved! Go to Solution.
I wasnt aware you didnt have a valid "next hop", the assumption was that you had.
I am quite sure a NAT rtr cannot translate to itself hence the failure, once you created a valid reachable "nexthop" then translation became appllicable.
