Hello. I have an EBGP link to my ISP from my ISP router. Internally Im running EIGRP. I have a 10. network and internally I have several vlans configured on a dist switch. Example.
VLAN 101 - 10.254.30.128/25
Vlan 102 - 10.44.80.0/24
VLAN 103 - 10.44.81.0/24
My first question is, on this dist switch, using EIGRP, if I configure network 10.0.0.0 and then include the no auto-summary command, will it give me all the granular routes in the routing table? If so, what is the benefit of configuring all these networks line by line in internal BGP (on the ISP facing router) and then redistributing them into EIGRP. example
Router bgp 64557
network 10.254.30.128 mask 255.255.255.128
network 10.44.80.0 mask 255.255.255.0
network 10.44.81.0 mask 255.255.255.0
router eigrp 64557
redistribute bgp 64687 metric 100000 1000 255 1 1500
My question is why redistribute from BGP to EIGRP? Why not let EIGRP learn to internal network, then redistribute its routes into BGP?
