Hmmmm....
The 3750 is mine but the GSR is owned by another ISP.
It's too risky to turn on OSPF, I think...

can you try to enable ospf on the interface. I reckon it will come up
(multicast traffic).

Subject: [c-nsp] GSR and 3750 GE-LX link problem
Hi,
I am recently working on a GE link between a GSR and a 3750.
The GSR side is GBIC-LX, the 3750 side is SFP-LX, and the
fiber is single mode. GSR in 32F, and 3750 is placed in 28F.
The GSR config is,
interface GigabitEthernet1/0
ip address 10.100.251.221 255.255.255.252
no ip directed-broadcast
end
The 3750 config is,
interface GigabitEthernet1/0/26
no switchport
ip address 10.100.251.222 255.255.255.252
end
When I plug the fiber, GSR and 3750 can see each other
by using "show cdp neighbor". Also, the MAC addresses
are correctly learned by each other.
BUT, the problem is they cannot ping each other.
After many many tried to change negotiation mode and made
loopback check. There is no problem on the fiber itself,
I am almost been driven to crazy.
Do you ever have such weird problem?
Regards,
Yu-lin
