[j-nsp] Ip share interface

[sunnyday]

hello
i have a question regarding giving  vpn access to the internet
i have seen one way to do it is via a shared ip interface.
host1(config)#virtual-router pe1:pe11host1:pe1:pe11(config)#interface ip internethost1:pe1:pe11(config-if)#ip share-interface gig 2/2.10host1:pe1:pe11(config-if)#ip address 10.1.1.3 255.255.255.255
host1:pe1:pe11(config-if)#exit
host1:pe1:pe11(config)#ip route 0.0.0.0 0.0.0.0 ip internet1 when i tried to configure it the shared interface was ethernet and it was not possible any ideas on a workaround?E310-Lab:vr2:vpn1(config)#ip route 0.0.0.0 0.0.0.0 ip internet% invalid next-hop for a multiaccess interface2 what the ip of the shared interface should be?in the range of the shared interface? or it doesnt matter what ip will i use?thanks in advance
