L3 interafce on Avaya 5530/4524 switch
« on: March 16, 2016, 09:23:45 AM »
Dear Team,

Can any interface can be created as L3 routed interface in Avaya 5530 or 4524 switch by giving an IP address, like in Juniper switch other than creating a vlan interface?

Thanks in advance.

Regards,
AN

Nope.  You have to create a VLAN and then assign an IP address to the VLAN.  Of course you can create a VLAN with just a single port in it

I remember only ERS8600 have this capability. Avaya L3 switches have no similar "no switchport" command like Cisco L3 switches.

Actually, brouter ports have been in place on the ers5x00/4x00 since times immemorial!

From the docs:
The Avaya Ethernet Routing Switch 5000 Series supports the configuration of brouter ports.
A brouter port is a single-port VLAN that can route IP packets as well as bridge all non-routable
traffic. The difference between a brouter port and a standard IP protocol-based VLAN
configured for routing is that the routing interface of the brouter port is not subject to the
spanning tree state of the port. A brouter port can be in the blocking state for non-routable
traffic and still route IP traffic. This feature removes interruptions caused by Spanning Tree
Protocol (STP) recalculations in routed traffic. A brouter port is actually a one-port VLAN;
therefore, each brouter port decreases the number of available VLANs by one and uses one
VLAN ID.


This is the cli needed to configure it:
brouter [port <brouter_port>] vlan <vid> subnet <ip_address/mask> [routing enable]

Enjoy!

Good find on that command.  I don't think I have ever seen it used though.  I just always made a VLAN and assigned a single port to it, which in effect is the exact same thing as that one command.

I have used it in the distant past, and will soon use it on a pair of VSP8400s. I'll be doing eBGP peering with ISIS External routes (VOSS 5.x feature), and a brouter port is part of the recommended settings from Ludovico. Like it states in the documentation, a brouter port is always open even if stp is blocking the port.
