Hi guys..
big question..
If on a Lab Im asked that All my local subnet networks should be update to BB1 except entire network (155.1.0.0/16), and the solution suggests:
topology:
-----155.1.x.0/24----- R1 --- 20.0.0.0/16 ---- BB1
solution:
ip prefix-list RIP_to_BB1 seq 5 deny 155.1.0.0/16
ip prefix-list RIP_to_BB1 seq 10 permit 0.0.0.0/0 le 32
router rip
version 2
redistribute ospf metric 1
network 20.0.0.0
distribute-list prefix RIP_to_BB1 out ethernet 0
no auto-summary
Ospf runs on 155.1.x.0
First question:
If Im asked for all my local subnets.. this means only to consider subnets of my network 155.1.0.0 in this case or whatever network My routers have direct connection to (for example the network that connects to internet).
second question:
If Im routing rip between my router and BB1 router, wouldnt be enough to active the no auto-summary command on my router to avoid sending the summarized network number 151.1.0.0/16??
third:
Isnt more efficient to rewrite the filters above like this:
ip prefix-list RIP_to_BB1 seq 5 permit 155.1.0.0/16 ge 17
thanks.
Your comments are highly appreciated.
