That is some crazy setup you have here :) So Carrier supporting Carriers has two ASNs AS100(r3+r1) and AS200(r2+r4) and r1 and r2 run MP-eBGP The Customer Carrier has also two ASNs AS100(r5+r6) and AS200(r9) and r5 and r9 run OSPF over the CsC and MP-eBGP on loopbacks carried in OSPF CEs are hooked up to the Customer Carrier r5 has RIP speaking CE r7 r6 has EIGRP speaking CE r8 r9 has RIP speaking CE r10
Basically the only weirdness is that RIP speaking CE(r7) doesn't see the loopback of EIGRP speaking CE r8 but it does see its PE-CE subnet (which is carried solely in EIGRP no redist. conn. In vrf BGP on PE). These two are even connected over a single Customer Carrier ASN 100. I don't know why these two can't see each other. Try posting the bgp tables from R5 and R6 so we can see where is the r8's loopback lost adam -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mohammad Khalil Sent: Thursday, April 11, 2013 9:38 AM To: [email protected] Subject: [c-nsp] EIGRP CsC I have configured CsC (inter-AS) with three sites (R7 , R8 and R10) R7 - R5 - R3 - R6 - R8 | R1 | R2 - R4 - R9 - R10 R1 operates in AS 100 , R2 operates in AS 200 Now , when i am running RIPv2 or BGP as the routing protocol between these CEs and their respective PEs all is functioning well (BGP VPNv4 sessions are established between R9 R5 , R6 R5) But when i am running EIGRP its not functioning !!
