2 VLAN MPLS/internet in single handoff question

I hope you guys can help me out here. I'm getting a single fiber handoff from our provider that 

has two vlans. One for internet and one for MPLS. I would like to bring them in to our core
isolated and hand them off to two other devices. ASA for internet and Router for MPLS. I
will attach a basic drawing of what I'm trying to do.

I'm able to get this workng going in to a Cisco Router with two sub interfaces just fine. I
have been unable to get it to work on the HP . The switch is an HP J9091A Switch E8212zl
Software revision K.15.07.0008.

Here's what I have for the config on the switch...


interface A1
name "WWW to ASA"
exit
interface A2
name "MPLS to ASR"
exit
interface E7
name "To MPLS/WWW NID"
exit


vlan 100
name "WWW VLAN"
untagged A1
Tagged E7
no ip address
exit

vlan 200
name "MPLS VLAN"
untagged A2
Tagged E7
no ip address
exit


This is the config on a Cisco 2921 that works.

 

interface GigabitEthernet0/1.100
encapsulation dot1Q 100
ip address yyy.yyy.yyy.yyy 255.255.255.252
!
interface GigabitEthernet0/1.200
encapsulation dot1Q 200
ip address xxx.xxx.xxx.xxx 255.255.255.252
!
interface GigabitEthernet0/2
description Simulated Existing Point to Point networks
ip address 10.254.254.1 255.255.0.0
duplex auto
speed auto
!

 

Am I approaching this right? Are there other ways to do this in an HP switch? This is the
forst of a handful of sites that need to have similar configurations. Any help would be
greatly appreciated!

 

Thanks,
Jon

Re: 2 VLAN MPLS/internet in single handoff question

Can you show us the config of interface E7? Only these two VLANs are tagged on that interface?

 

Is your ISP using Cisco at their end? We have about the same setup as you, but we use 5900 switches and we had to include VLAN1 also on the port connecting to the ISP. Like this:

 

interface Ten-GigabitEthernet4/0/44
 port link-mode bridge
 description Link to ISP
 port link-type trunk
 port trunk permit vlan 1 xxx yyy

The obvious difference between your Cisco config and your HP config is that you have IP addresses configured on your Cisco VLAN100 & VLAN200 subinterfaces but you do not have those IP addresses configured on the HP VLAN 100 & 200 interfaces.
