EIGRP

HI

I have advertised a Network via EIGRP to site-3 from the Core.but when advertised the network;site-7 learned all the Networks;vlan in the enterprise network from the core.i dont need the overload in the site7 also in the other site to learn every networks;vlan in the networks.how can i achive that?if i use distr-list with access-list when should i run the dist-list.simple config very much appreciated.

Re: EIGRP

it would look something like the following:

R(config)# access-list 1 permit 0.0.0.0

R(config)# access-list 1 permit 10.10.10.0

R(config)# access-list 1 deny 0.0.0.0 255.255.255.255

R(config)# router eigrp 1

R(config-router)# network 10.10.10.0

R(config-router)# distribute-list 1 in

the above commands will allow only the two defined networks to be advertised into eigrp. you can put something like this on your remote routers. or you can filter outbound advertisements as well from the core router.

see link below for more info:

Re: EIGRP

you can put this small list as i've shown on a remote site router or nonCore stub type of network.

you can use the outbound distribute-list on a core router to prevent it from advertising more networks than you'd like it to.

Re: EIGRP

will u clear me the first and syntex of permit and then last syntex of deny ...what is the logic behind this.
