[nsp] 75xx with VIP2-50 and PA-GE running MPLS VPN's?

[Dennis Dubbelman]

Strange is that packet leaving the box is working :
 
per2.asd-hp.nl#ping vrf internet www.cisco.com
Translating " www.cisco.com"...domain <http://www.cisco.com>  server (172.31.1.1) [OK]
 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 198.133.219.25, timeout is 2 seconds:

use 'tag-switching mtu' on the interface to allow for the tags/labels to be added
 
if it does not help then you're probably affected with some old bugs - either upgrade or increase physical mtu (if possible, e.g. on serial)

Hi, 

We've got a 7513 with a VIP2-50 and a PA-GE inserted into it ?!?! 
We would like to use the box and run MPLS VPN's across it. 
The strange thing I see is when I ping with a 1500 bytes packet from an other Cisco box to the loopback of the box everything looks oke.

But when I ping from a windows station to the loopback with a 1500 bytes packet we see the following: 

Feb 27 17:40:14: %LINK-4-TOOBIG: Interface GigabitEthernet0/0/0, Output packet size of 1554 bytes too big 
-Traceback= 40408DAC 4033D33C 40225B08 4022584C 4055B2C8 4055B8FC 4056CC64 4056EFCC 4054FE9C 4054DF08 4054E038 4054E204 4036B72C 4036B718

It looks that the packet is coming in oke, but the icmp reply is dropped ! 

Does anyone know the difference between the two pings ? 
What is the difference between a GEIP and a VIP2-50 and a PA-GE ? 
Can a VIP2-50 handle a PA-GE or do I need a GEIP ? 

Thanks in advance. 

/Dennis
