Ipv6 routing rip

admin_2 · ‎04-05-2004

Hi,

Tryin to setup a ipv6 testlab with 2 cisco3600 routers(1serial,2ethernet) connected with 2 serial cables with 2 hosts on each side of network.

Assigned ipv6 addresses to all needed interfaces and on both sides all works wel exept the rip routing proces.(The basic setup works cause last week i did same setup with ipv4 and it worked fine.)

When working with ipv4 it was needed to add a route with the network command but where did it go in ipv6?

i enable a routing rip proces on the ethernet and serial interfaces but when i do a sh ipv6 routing rip no routes show up.All protocols and lines are up but i canot seems to go to the other side of the network.Any help would be appricited.txs.

The way to configure RIP under ipv6 is a bit different than under ipv4. You have to enable RIPv6 on a per interfaces basis in the following way.

int e0/0

ipv6 rip TEST enable

ipv6 router rip test

Do a "sh ipv6 rip" to see if RIPv6 has been interface on your all the desired interfaces.

Hope this helps,

I meant "if RIPv6 has been enabled on all the desired interfaces"

I haven't had my first coffee yet ;o)

If i do a sh ipv6 rip it sais that its enablede on both interfaces (fastethernet & serial) ut that doesn't mean it works.. i have no connection to the other network.

Serial0/0 on router0:global uicast addres: 2001:b78::a1:b2:c3:1/32

serial 2/0 on router2:

2001:b78::a1:b2:c3:2/32

I can ping both serial interfaces from the console of the routers but if i try to ping beyond serial aka ethernet it wont go thru.. weird..If i look into the manuals its a piece of cake but i didn't had cake yet :) ... any other ideas?I'll try to post my run 2 night.

You configured the same prefix (3FFE:C00:C18:C1::/64 ) on both LAN interfaces. RIPv6 advertises the prefix from one side to the other but it is not installed on the receiving router because of the connected route for that prefix. Try configuring 3FFE:C00:C18:C2::/64 on router02. This should fix it.

Hope this helps,
