Janez, you are awesome! That did it. I tried with only dhcp relay profile and didn't work, then I also added back the interface level ip helper vrf one (not vrf default, like it defaulted to originally) and BANG!
Thanks again. Huge Help Janez Aaron conf dhcp ipv4 profile test relay helper-address vrf one 192.168.254.13 interface BVI10 vrf one ipv4 helper-address vrf one 192.168.254.13 ipv4 address 5.6.7.8 255.255.252.0 ipv4 address 1.2.3.4 255.255.255.0 secondary commit -----Original Message----- From: Janez Novak [mailto:jnovak...@gmail.com] Sent: Tuesday, June 05, 2012 4:54 PM To: Aaron Subject: Re: [c-nsp] ip helper within L3VPN Hi Aaron, Use VRF in helper address command as you mentioned it otherwise it leaks into global routing table. If it still does not work try following documentation :-) http://www.cisco.com/en/US/docs/routers/asr9000/software/asr9k_r4.2/addr_ser v/configuration/guide/b_ipaddr_cg42a9k_chapter_0100.html#con_1096525 Regards, Bostjan On Tue, Jun 5, 2012 at 10:39 PM, Aaron <aar...@gvtc.com> wrote: > I'm having trouble getting dhcp ip helper to work (ip helper on a vrf > interface of a asr9k 4.1.2) > > > > Dhcp server------ce1----pe1---p1-----p2-----p3-----pe2-------dhcp > client locally connected subnet > > > > I would think that pe2 wound need to have ip helper on the interface > that is locally connected to dhcp client as usual with ip helper. > > > > When I put ip helper on that interface it default to "vrf > default"...even though the interface is BVI10 - vrf one > > > > Is that supposed to be that way ? > > > > I mean if I have my dhcp server on the other side of that l3vpn, > should the ip helper statement be ipv4 helper 1.1.1.1 vrf one 192.168.100.1 ? > > > > Also, is there something else I need to do to make this work?
