Configure A Designated Router; Create Multicast Boundaries And Domains - Dell Force10 C150 Configuration Manual

Configure a Designated Router

Multiple PIM-SM routers might be connected to a single LAN segment. One of these routers is elected to
act on behalf of directly connected hosts. This router is the Designated Router (DR).
The DR is elected using hello messages. Each PIM router learns about its neighbors by periodically
sending a hello message out of each PIM-enabled interface. Hello messages contain the IP address of the
interface out of which it is sent and a DR priority value. The router with the greatest priority value is the
DR. If the priority value is the same for two routers, then the router with the greatest IP address is the DR.
By default the DR priority value is 192, so the IP address determines the DR.
IP Version Task
IPv4 Assign a DR priority value.
IPv4 Change the interval at which a router sends
hello messages.
IPv4 Display the current value of DR parameters.
IPv6 Assign a DR priority value.
IPv6 Change the interval at which a router sends
hello messages.
IPv6 Display the current value of DR parameters.

Create Multicast Boundaries and Domains

A PIM domain is a contiguous set of routers that all implement PIM and are configured to operate within a
common boundary defined by PIM Multicast Border Routers (PMBRs). PMBRs connect each PIM
domain to the rest of the internet.
Create multicast boundaries and domains by filtering inbound and outbound Bootstrap Router (BSR)
messages per interface, using the [
subsequent inbound and outbound updates. Already existing BSR advertisements are removed by timeout.
Remove candidate RP advertisements using the
