Hey Erik,
1) This messes up the design and introduces unnecessary complexity. As your
issue is not directly caused by having a RR topology, I’d avoid doing that.
2) That, IMHO, would be the optimal solution, assuming you don’t have enough
internal routes to overflow the TCAM of your PEs in the n

Hello,
In order to accept only the default route, I assume that you want to have
internet access to the ASR920 inside a vrf. ?!?
If this is the case, your consideration of the default route and the TCAM size
is correct. But, if there is internet traffic between the PE2-PE3 in the same
vrf , th

If I have understood your design correctly then don't use

Erik,
Before I email my suggestions, can you clarify the followings;
Do Core1 and Core2 also provide the function of BDRs peering with your
upstream/s?
Or
Just acting as Core/RRs with 500Mbps of traffic traversing through them?
Cheers

You could optimize the packet hop count by making smaller
but more rings. For example, make one ring with
CORE1, CORE2, PE1, PE2, PE3.
And another ring with
CORE1, CORE2, PE4, PE5.
If you configure "route-reflector-client" on the CORE,
and mesh the clients, then you can additionally configure

Ahad,
The Cores have
Connections to other POPs
Transiting
IX circuits connected on them
Also have some Customer on them so they do also act like a PE.
Thanks
