Hi guys,
I'm having rather hard time finding what's wrong in seemingly stupid
situation:
!
interface FastEthernet0/0
ip address <real ip address> 255.255.255.128
no ip directed-broadcast
full-duplex
!
interface FastEthernet0/0.1
no ip redirects
no ip directed-broadcast
!
interface FastEthernet0/0.77
encapsulation dot1Q 77
ip address 10.1.1.5 255.255.255.252
no ip directed-broadcast
!
(I've tried no ip address on maininterface and f0/0.1 in dit1q vlan 1,
result is the same).
7206-vpn-test#ping 10.1.1.6
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.6, timeout is 2 seconds:

I've tried to change dot1q to ISL, and result is the same, "encapsulation
failed". FE works fine, if I don't use VLAN's. I've tried different IOS
sets, too. Oh, yes. And a different router. First was 7206vxr with npe300
and dual FE IO controller, this current one is 7206 with npe200 and vanilla
IO controller. No difference.
Switch side I presume is not guilty, as this very same switch runs a few
dot1 trunks to other switches without problem. Switch is Cat2948, so it only
supports dot1q trunks. Switch and router perfectly see each other on cdp
neighbor list, too.
7206-vpn-test#sh int f0/0.77
FastEthernet0/0.77 is up, line protocol is up
Hardware is DEC21140A, address is 0004.de2f.8000 (bia 0004.de2f.8000)
Internet address is 10.1.1.5/30
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation 802.1Q Virtual LAN, Vlan ID 77.
ARP type: ARPA, ARP Timeout 04:00:00
It seem to recognize that it's a VLAN interface, too...
There is nothing really I can think of now, and what the hell should I think
of? This is a simple configuration, as simple as it gets, and I had it
working in dozens of other places. :( Any ideas?
