Ospf - Avaya P333R User Manual

RIPv1. The most important change in RIPv2 is the addition of a subnet mask field
which allows RIPv2 to support variable length subnets. RIPv2 also includes an
authentication mechanism similar to the one used in OSPF.
Configuration of the RIP version, 1 or 2, is per IP interface (default is version 1).
Configuration should be homogenous on all routers on each subnet, i.e. there
should not be both RIPv1 and RIPv2 routers on the same subnet. However, different
IP interfaces of the P333R can be configured with different RIP versions (as long as
all routers on the subnet are configured to the same version).
RIPv2 and RIPv1 are considered the same protocol with regard to redistribution to/
from OSPF and static route preferences.

OSPF

P333R supports the OSPF routing protocol. P333R can be configured as an OSPF
Autonomous System Boundary Router (ASBR) by configuration of route
redistribution. P333R can be installed in the OSPF backbone area (area 0.0.0.0) or in
any OSPF area that is part of a multiple areas network. However, P333R cannot be
configured to be an OSPF area border router itself.
The P333R supports the equal-cost multipath (ECMP) feature which allows load
balancing by splitting traffic between several equivalent paths.
While OSPF can be activated with default values for each interface using a single
command, many of the OSPF parameters are configurable.
For a detailed description of OSPF, refer to the OSPF standards and published
literature.
