    BGP Default Route

    There is no reply yet :-( pls answer it
  4. HI every body, Hope you all will be fine. I have a question regarding BGP default route but before this let me explain the scenario. We have a metro ethernet network with 5 POPs (7609) connected with fiber dual ring, IGP in use is ISIS and also MPBGP being used for carrying MPLS VPN routes. Further more lets assume 5 routers are like A,B,C,D,E, network design is like A and B are route reflectors and C,D,E are route reflector clients of A and B. Also C,D (route reflector clients) and A (route reflector) have EBGP sessions with uplink service provider for advertment of IP classes. EBGP connectivity of C,D and A is with two uplink carriers and its also redundant i.e D has two EBGP sessions with X uplink service provider and A,C has EBGP sessions with Y(uplink provider). in short both EBGP sessions with X are terminating on D and Y has one EBGP session with C and other with D (BGP path attributes being used for influencing out and in traffic) now the question is we have configured static default routes on C pointing towards Y and through command of default-information originate this is redistributed in whole network. The question is I want to get default routes from all uplink providers through BGP and propagate it in whole network but in a way if EBGP interface of C goes down than internet traffic shouldnt be disturbed, immediately default routes of D or A should take place in routing table. Please help how can i achieve this, what will i have to do, should i redistribute EBGP learned default route into ISIS or should i use BGP path attributes for preferring one default route over the other. Please answer in detail...........Thanks in advance. Qamar Zia
  5. Kindly inform which DOC_CD ?
  6. Hi every body, I am confused between backplane capacity and throughput terms. Can any body explain differences between two in simple words. Also whats the backplane capacity and throughput of cisco 7609 router with SUP 720 route process (per line card and in total) ? Thanks, Kami

    Virtual Template

    Dear All, I have a question that why do we use virtual template ? And also the command ip un-numbered loopback 0 or gig0/1 is always used, can we assign this virtual template IP like other interfaces. We have a BRAS connecting PPPoE sessions and i cant find the good explanation of this question. Please help. Kami
