It is possible ssh from a router to another, to its ipv6 link-local address?

[cesar.gonzalez.m]

Hi 

R1 and R2 are connected by serial links, with IPV6 address global unicast and link-local every link.

I can do ping between them. When I do ping to link-local address next router, I need to specify outgoing interface, ping is succesful.

However I can not do SSH v2 from a router to another to its link-local address. 

OS R1 and R2: c2900-universalk9-mz.SPA.151-1.M4.bin 

R1

Serial0/3/0                [up/up]
    FE80::1
    2001:1200:CAFE:BEBA::1

R2

Serial0/3/0                [up/up]
    FE80::2
    2001:1200:CAFE:BEBA::2

Thank you

Hi Cesar,

The IOS SSH command does not let you specify a source interface, therefore the router will not be able to work out whch interface the destiantion FE80 address can be reached on.

You will need to use the other routers global unicast address.

cheers,

Seb.

Hi Cesar, 

you should be able to use "%source_itf" at the end of the target IPv6 LL address. 

Example with telnet : 

R1#ping FE80::302              
Output Interface: Ethernet0/0                 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FE80::302, timeout is 2 seconds:
Packet sent with a source address of FE80::301%Ethernet0/0
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/1 ms
R1#telnet FE80::302%Ethernet0/0
Trying FE80::302 ... Open

Password required, but none set

[Connection to FE80::302%Ethernet0/0 closed by foreign host]
