Layer 2 tracemroute
Release 3.1 adds the l2tracemroute command to trace the multicast tree for a given
multicast flow.
Transparent UNI
Release 3.1 support Transparent UNI feature. A Transparent UNI (T-UNI) maps an entire port
or MLT to an I-SID. On Transparent UNI, ISID untagged and tagged(802.1q) packets are Layer
2–switched and the forwarding decision is based only on the MAC Addresses; VLAN ID is not
used.
You can map multiple ports to a T-UNI I-SID. Multiple ports of the same switch or of different
switches can be mapped to same Transparent UNI I-SID.
L3 protocol support
OSPF and RIP:
Release 3.1 introduces support for the configuration of the Open Shortest Path First
(OSPF) and the Routing Information Protocol (RIP) on the Avaya VSP 4000.
OSPF is an Interior Gateway Protocol (IGP) that distributes routing information between
routers that belong to a single autonomous system (AS). Intended for use in large
networks, OSPF is a link-state protocol that supports IP subnets, Type of Service (TOS)-
based routing, and tagging of externally-derived routing information.
In routed environments, routers communicate with one another to track available routes.
Routers can dynamically learn about available routes using the RIP. The Avaya VSP 4000
software implements standard RIP to exchange IP route information with other routers.
For more information, see the Avaya Virtual Services Platform 4000 Configuration —
OSPF and RIP, NN46251–506.
BGP :
Release 3.1 also introduces support for the configuration of Border Gateway Protocol
(BGP) on the Avaya VSP 4000.
The following operations are supported by BGP:
- ipv4
- 4 byte AS
- Peer groups
- Redistribution

BGP, NN46251–507.
