[c-nsp] DHCP route on VRF enabled interface.

[victor]

Hi guys,

Maybe someone would know why when router receives DHCP offer on a vrf
interface the default route (option 3) gets installed in the main routing
table and NOT in the corresponding VRF? Here is a piece of config and show
ip route outputs:


ip vrf asd
    rd 1:1
!
interface FastEthernet1
    ip vrf forwarding asd
    ip address dhcp
    duplex auto
    speed auto
!
!

Router#sho ver | in flash:
System image file is "flash:c181x-advipservicesk9-mz.124-6.T11.bin"

Router#sho ip route
....
Gateway of last resort is 192.168.3.1 to network 0.0.0.0

        192.168.3.0/32 is subnetted, 1 subnets
S       192.168.3.1 [254/0] via 192.168.3.1, FastEthernet1
S*   0.0.0.0/0 [254/0] via 192.168.3.1


Router#sho ip route vrf asd

Routing Table: asd
....

Gateway of last resort is not set

C    192.168.3.0/24 is directly connected, FastEthernet1
Router#


For now to avoid confusion I removed default router offer with "no ip dhcp
client request router" that means that I need to make sure that a correct
default route is installed manually. But it doesn't work very well because
the leased subnet changes periodically. So I'm looking for a way to make
cisco dhcp client vrf aware. Your suggestions are appreciated.

Thanks

Victor
