I have a RR Client design question...... CORE1-------------------2x10G-----------------------CORE2 | | | | | 10G Ring | | | | | PE1----------PE2----------PE3----------PE4----------PE5 -Core1 & Core2 are RR Reflectors with full IPV4 Tables (ASR9K) -MPLS LDP Enabled -IGP is ISIS -Each PE peers only with Core1 and Core2 as RR Clients with iBGP -PE's are only receiving a default route from the Core Routers due to TCAM size of 20K (ASR920's\ME3800's) -The ring does not have that much traffic on it <500m, so I do not want to use additional 10G ports on the Core's and is why I have it in a 10G U ring. -Primary link to the cores is via the PE1 --- CORE1 Like......... For this discussion the link between PE5 to CORE2 is set up as a backup link. The scenario is I have traffic between PE2 and PE3. Since the PE's are only receiving a default route from the Cores. Traffic is label switch from PE2 - PE1 - Core1 does a IP lookup at Ingress then label switches back to PE1-PE2-PE3. This ends up being 5 hops and doubling the traffic on the link to the Cores. My questions is how do I get traffic to go directly between the PE's without going to the Core Routers? 1. Can I enable iBGP between the PE's in a full mesh to allow traffic between the PE's without going to the core's. Or does this break the Route Reflector model? 2. Create a route policy on the Core's advertising routes learned from the PE's back to all the PE's on the ring. 3. Is this one of the down sides to U Rings? 4. Leave it alone and move on to bigger and better things....
