Ipv6 Serial Interface Configuration Not Working Cisco Community I am configuring ipv6 in gns3 lab environment for studying and when i configured the ip address, in fa0 0 and s0 0 on both routers (r1 and r4) the serial interface goes up up for a few seconds and then it goes up down and i am unable to ping the other side of the serial interface. Solved: i cant configure ipv6 in the router. the command ipv6 is not available! see the version screen shot cisco ios software, 1841 software (c1841 ipbase m), version 15.1(1)t, release software (fc1) technical support:.
Ipv6 Error Message On Cisco Asa When Creating A Tunnel Interface Here is a fast synopsis of the issue: when pinging from the ethernet side of the router, the serial interface does not pass the ipv6 traffic out. when pinging from the serial interface to another router, the destination router will not pass the ipv6 traffic through to ethernet, but it will send a reply if a ping is done to the serial interface. For a lab i need to configure ipv6 between two router (1841 & 1941) i setup link local on serial interface on both router. i setup static routing route. it is working fine, i can ping across router but when a save my network, quit and reload the file. I just recently bought a new cisco 2611 for my home lab and am having trouble getting the serial port to work. i have tried multiple things such as erase startup, switching the cables to rule them out, and even changing ip addresses but none worked. Martin, pings work when i change the static routes to use a next hop ipv6 address; instead of the outgoing interface is this a known issue, or is this gns3? in any case, that's the fix.

The serial interfaces don't have mac address so even if you configure it to have one, the router won't use it to make the ipv6 link local address. the router uses another method that should allow both links to still come up with unique link local address. I tried to configure ipv6 static routing on three routers, i configured ipv6 addresses on all three routers using ipv6 address auto config, the middle router have been configured with different glo. I have two routers connected with serial interfaces and to begin with i was unable to ping either router, anyway i want to configure ospf 100 with the routers on area 0 the current configs are router 1:. You have some configurations that do not correspond in the link between the routers. in short, your interfaces should look like this: router1. interface serial0 3 1. bandwidth 64. no ip address. ipv6 address fe80::1 link local. ipv6 address 2001:ad3:abcd:8::1 64. ipv6 ospf 1 area 0. clock rate 64000! router2. interface serial0 3 0. bandwidth 64.
