hp 6600 Series router irb (bridge mode)

[rodtor]

Hello, I am a network engineer in Korea. The equipment in charge is the hp 6600 series router. I'm not good at English, so I'm asking you a question using a translator.

Cisco router has settings called irb, bridge mode. I wonder if the router I'm in charge of has the same command. First of all, Cisco Router command.

int fas0/0 

no ip address

bridge-group 1

int fas0/1

no ip address

bridge-group 1

bridge-group1 protocol ieee

brdige-group1 route ip

int bvi1

ip address x.x.x.1 255.255.255.0

no shut

I'll leave a link just in case.

Thank you. 감사합니다.

Hello,

I believe you are looking for route aggrgation in HP routers.

Config would be like below:

interface <interface number>

port link-mode 

port link-aggregation group 1

quit

Repeat same for other interface.

interface route-aggragtion 1

ip address <ip address>

quit

Do checks:

display route-aggragtion 1

display link-aggregation verbose

Thanks!

quit

Hello @rodtor !

As far as I know there is no way in 6600 to bridge several L3 interfaces into one broadcast domain. If a port is in L3 mode (port link-mode route) it is a broadcast domain on its own and you can't bridge it with another L3 interface. What you can do, however, is to convert those ports to L2 mode (port link-mode bridge), then make them access mode in a VLAN and on the top create an SVI (Vlan-interface) for the respective VLAN (it will be like BVI interface in Cisco). But there is a drawback - not all ports in 6600 can be switched to L2 mode. Here is what the Interface Configuration Guide says:

This feature is supported on only routers configured with SAP modules.
Depending on the hardware structure of interface cards, for a device, some interfaces can operate only as Layer 2 Ethernet interfaces (in bridge mode), some can operate only as Layer 3 Ethernet 5interfaces (in route mode), but others can operate either as Layer 2 or Layer 3 Ethernet interfaces (you can set the link mode to bridge or route).

If the configuration is supported, it will look like:

int Gig1/0/1
 port link-mode bridge
 port link-type access
 port access vlan 999
#
int Gig1/0/2
 port link-mode bridge
 port link-type access
 port access vlan 999
#
int Vlan-interface999
 ip address x.x.x.1 255.255.255.0
 undo shut

I think this is the closest to Cisco's IRB concept you can get on 6600.

Hope this helps!

Thank you very much!!

Cisco is
bridge-group1 protocol ieee

brdige-group1 route ip
Do I not need to set the protocol and routing separately for HP?

No, these commands do not have analogue in Comware, but you don't really need them. If your router's ports support 'port link-mode bridge', the configuration I've provided you in my previous message is sufficient.

Thank you for the information. That was a great help.
