[nsp] 7600 and 12.1(20)E - first impressions

[sthaug at nethelp.no]

We now have our first 7609 PE router up and running with 12.1(20)E. I'm
afraid there are definitely problems here still. This is the hardware:

Mod Ports Card Type                              Model              Serial No.

Some issues are cosmetic, e.g. "Gbic not connected" for an interface that
is very much up and running:

trondh-PRINSG39-pe1#sh in ge4/3
GE-WAN4/3 is up, line protocol is up
  Hardware is GigabitEthernet Interface, address is 0009.b695.804a (bia 0009.b695.804a)

Here we also see counter problems - a GigE interface with 3.23 Gbps of
traffic? :-)

More serious for us is that some 802.1q subinterfaces aren't assigned
SNMP ifIndexes. Of the following two interfaces:

interface GE-WAN4/3.16
 encapsulation dot1Q 16
 ip vrf forwarding V119:internett
 ip address 195.204.197.1 255.255.255.0
!
interface GE-WAN4/3.19
 encapsulation dot1Q 19
 ip vrf forwarding V119:internett
 ip address 195.204.251.217 255.255.255.252

the first doesn't show up on an snmpwalk, while the second does.
