21 RRD
RRD (Route Redistribution) allows different routing protocols to exchange routing information. Using a
routing protocol to advertise routes that are learnt by other means, such as, another routing protocol,
static routes, or directly connected routes, is called redistribution. While running a single routing protocol
throughout an entire IP internetwork is desirable, multi-protocol routing is widespread for a number of
reasons, for example, company mergers, multiple departments managed by multiple network
administrators, and multi-vendor environments. If a single routing protocol cannot be used, route
redistribution is the only solution. Running different routing protocols is often part of a network design. In
any case, having a multiple protocol environment makes redistribution a necessity.
Each routing protocol on a network is separated into an autonomous system (AS). All routers in the same
autonomous system (running the same routing protocol) have complete knowledge of the entire AS. A
router that connects two (or more) autonomous systems is known as a border router. A border router
advertises routing information from one AS to the other AS(s). It is only possible to redistribute routing
information for like routed protocols. Different routing protocols have different, and often incompatible
algorithms and metrics.
The list of CLI commands for the configuration of RRD is as follows:
as-num
router-id
export ospf
redistribute-policy
default redistribute-policy
show ip protocols
show redistribute-policy
show redistribute information
