Rip; Ripv2 - Siemens SCALANCE XM-400 Configuration Manual

LSA types
Two new LSA types were defined for OSPFv3.
OSPFv2 OSPFv3
1 Router LSA 0x2001
2 Network LSA 0x2002
3 Summary 0x2003
LSA
4 AS Summary 0x2004
LSA
5 AS External 0x4005
LSA
7 NSSA Exter‐ 0x2007
nal LSA
0x2008
0x2009
In contrast to OSPFv2, OSPFv3 can forward unknown LSA types. Previously these were
deleted and not distributed further.

RIPv2

Dynamic routing with RIPv2
The Routing Information Protocol (RIPv2) is used to create routing tables automatically. RIPv2
is used in autonomous systems (AS) with a maximum of 15 routers. It is based on the Distance-
Vector algorithm.
RIPv2 was developed by the IETF (Internet Engineering Task Force) and is described in RFC
2453.
You configure RIPv2 in "Layer 3 (IPv4) > RIPv2".
Setting up a routing table
Since a router initially only knows its directly connected networks, it sends a request to its direct
neighbor routers. As the reply, it receives the routing tables of the neighbor routers. Based on
the information it receives, the router set up its own routing table.
The routing table contains entries for all possible destinations. Each entry includes the distance
to the destination and the first router on the route.

The LSA is sent by the router to every router linked to it. The
LSA contains the link local address of the router and a list
with IPv6 prefixes configured on the link.
The LSA is sent only within an area. The LSA contains the
IPv6 prefixes connected to the router or network.
