Assuming 4 nodes - A, B, C, and D, connected in SONET ring running UPSR. According to a Cisco press book, if a STS is mapped between two nodes (say A and B), then that STS is consumed for the entire ring and cannont be used to add/drop traffic elsewh...
Has anyone successfully deployed RightFax in this scenario? I have one voice gateway connected to the PSTN via a PRI, and another (non-PSTN) PRI to the Cisco Fax server's brooktrout card. Voice and fax both have their DID ranges. I want fax call to c...
I have gone through a couple of white papers on deploying hub and spoke over MPLS VPN. While the use of two different RTs make sense to me, I am not sure why you would need two different (physical or logical) interfaces to the hub CE.I have heard it'...
A customer wants to do a "hub and spoke" overlay on MPLS VPN. Currently, they have two hub routers, each passing a default route (using EIGRP summary-address command) to the spoke.After switching over to MPLS VPN, they are experiencing problems in th...
Is there any official specification that anyone knows regarding MFR and frame/ATM internetworking compatibility?In other words, if you have a CPE running MFR to a FR/ATM switch, and from that switch you have an ATM connection to another CPE, will tha...

I am not sure I follow what you guys are saying. On PE1, it will get two default routes: one coming from hub1 via EIGRP, and one coming from PE2 via IBGP. PE1 will install the EIGRP default route because of better AD. The default route will then be r...
