Multi-VFR problem

In the Multi-VRF documents and the sample configurations, I can see the physical link between the PE and the Multi-VRF CE is always divided into multiple sub-interfaces such as trunking, T1 sub-interfaces and so on. Is this required to configure Multi-VRF because this is the only way to map the traffic to a specific VRF? If it is the case, how can we support the Multi-VRF when the physical link between the PE router and CE router is the ethernet or HDLC which can not be divided to sub-interfaces? And if I can configure the trunk between two routers?

Thanks

Re: Multi-VFR problem

All Cisco 1700 routers (except the 1710) supports multi-VRF on all their interfaces. (Refer to http://www.cisco.com/en/US/products/hw/routers/ps259/prod_bulletin09186a0080107ce5.html under the section Multi-VRF Platform Support)

You might also want to look at the document 'OSPF support for Multi-VRF on CE Routers'. This document is available at the URL http://www.cisco.com/en/US/products/sw/iosswrel/ps1612/products_feature_guide09186a00800ad917.html#70128.

Re: Multi-VFR problem

I ever have a look about these two documents, but I can not find any more configuration document regarding the Multi-VRF on the routers. And I want to know when I configured Multi-VRF on PE and CE routers, if I must use sub-interfaces on the PE and CE routers. Becasue it seems the only way to distinguish the traffic for different VRF. Thanks
