[j-nsp] ISIS adjacency on the GigE interface

[Johnny Kui]

Hi Sorin,
 
I went ahead and set the mtu on the interface. The show commands show the correct MTU:
 
> show configuration interfaces ge-1/2/0.0 family iso 
mtu 1497;
 
> show interfaces ge-1/2/0.0 media | match iso 
    Protocol iso, MTU: 1497

But the adjacency is still not coming up.
 
Thanks,
John

Hi,

Take care to the CLNS MTU for the GE Interface. ISIS paddes the ISIS 
hello packet to the MTU of the GE.

You can set the MTU for CLNS on the interface to a value usable by the 
other routers' interfaces:

> show interfaces ge-0/0/0.11 media | match iso
Protocol iso, MTU: 1497

> show configuration interfaces ge-0/0/0.11 family iso
mtu 1497;

When turn on the traceoptions, I can only see the M10 sending out hello packets but not receiving any hello packets. Am I missing any configurations on the GigE interface? The Juniper M10 is running version 6.2R1.5.
