    Task 5.3 - NLRI Advertisement

    Hi,

    Why redistribute connected on R5? Is that to get the Eth0/0.1 and 0/0.2 in BGP as well?

    I think yes, as well as for s0/1. But here comes the trick - R5 will relay this prefixes to BB2 and BB3 since it will receive 'em from R6, so 'red ei 10' under BGP should be ok. However, SG approach looks more confident.

    1.) Why is there a need to redistribute EIGRP into BGP on R5 and R6? Wouldnt a single redistribution on R5 is sufficient enough?

    2.) how does the ODR routes on R5 gets redistributed in BGP?

    I can see the ODR routes in R5 routing table, but after redistributed EIGRP and Connected into BGP on R5. There are no BGP routes for R4 E0/0 an E0/1.

    Rack1R5#sh ip route od

    o       156.1.4.0/24 [160/1] via 156.1.45.4, 00:00:50, Serial1/1
