Help!
I can not bring up the session using link-local address on a p2p link!
While it is ok on ethernet.

N.B.:
- I can ping the peer:

r3#ping ipv6 FE80::20F:24FF:FEAB:B060
Output Interface: Serial0/0.324
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to FE80::20F:24FF:FEAB:B060, timeout is 2
seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/29/32 ms

- But I can NOT telnet it:

r3#telnet FE80::20F:24FF:FEAB:B060 /source-interface Serial0/0.324
Trying FE80::20F:24FF:FEAB:B060 ...
% Connection timed out; remote host not responding
