Logical representation of ISR within HP routing switch
Routing between the VLANs is performed without dedicating physical ports by using virtual interfaces. These
virtual interfaces serve as a link between the configured VLANs and the routing core of the HP routing switch.
The ISR architecture provides the platform for support of policy-based VLANs within HP routing switches.

IP/RIP Routing

IP is the most widely used networking protocol on the Internet and in enterprise LANs. The HP implementation of
IP adheres to the IP-related RFCs listed in "Software Specifications" on page B-1. In addition, features such as
multi-netting, integrated switch-routing, and VLANs (described in the sections above) enhance the IP support.
HP routing switches support the following intra-domain routing protocols:
RIP
OSPF
NOTE: An intra-domain protocol is a protocol that is used by routers under common administrative control. The
term "domain", used in this context, is synonymous with "autonomous system". In contrast, Border Gateway
Protocol (BGP) is an example of an inter-domain protocol. BGP is used by routers in one domain to exchange
information with routers in other domains.
RIP
RIP is a distance-vector protocol. It uses a cost value associated with each route to express the preferability of
that route. Generally, the cost is equivalent to the number of hops in the route, but HP devices allow you to bias
the preferability of a route by changing its cost. You also can configure the routing switch to prefer one route over
another equal cost route.
By default, HP routing switches using RIP propagate route information to other RIP routers by sending route
updates every 30 seconds. You can change this update interval if needed.
You can enable HP routing switches to use RIP version 1, RIP version 1 with version 2 compatibility, or RIP
version 2 to manage IP routes. The default is version 2.
See the "Configuring IP" and "Configuring RIP" chapters in the Advanced Configuration and Management Guide
for information.
Open Shortest Path First (OSPF) Routing
OSPF is a link-state routing protocol. Each router that runs OSPF uses information from its own interfaces and
from other OSPF routers to build a topological map of the network. OSPF routers exchange link-state databases
and then periodically send link-state advertisements to notify other routers of route changes.
