Title: Simple MPLS Test Lab

I'm looking to replicate a simple SP network to be able to test GRE tunnels for multicast music-on-hold. Even though the lab is completely Cisco I want adhere to open standards and maintain as near realistic SP type config as possible.

The lab is made up of:

CE1 belonging to company CH in vrf CH - running rip v2 with a default gateway to s0/0 the int. to PE1
CE2 belonging to company BH in vrf BH - running rip v2 with a default gateway to s0/0 the int. to PE1
1 PE1 running rip v2, bgp & ISIS
P1 running bgp & ISIS
P2 running bgp & ISIS
PE2 running rip v2, bgp & ISIS
CE3 belonging to company CH in vrf CH - running rip v2 with a default gateway to s0/0 the int. to PE2
CE4 belonging to company BH in vrf BH - running rip v2 with a default gateway to s0/0 the int. to PE2

I started using the Cisco Implementing MPLS courseware but found the labs overly complicated for what I'm trying to achieve. The issue I have at the moment is the courseware suggests that I should redistribute BGP back into rip, but to be honest the way I wanted it to work was that the CE's ran a static gw to the PE (it is it's only route out and if it has two I'll weight one of them), packet hits the PE which has full BGP/ISIS routing tables, packet passes through P nodes to PE2, which pops and looks up rip table to pass to appropriate CE.

I would be grateful for your comments on this design, protocol selection (I understand Cisco are working on allowing eigrp) and design tips

Yours

Doug
