Description
Using the reset pim routing-table command, you can clear PIM route entry.
The sequence of group-address and source-address can be reversed, but the input
group-address and source-address must be valid. Otherwise, the system will
prompt input error.
If group-address is configured to 244.0.0.0/24 and source-address to RP address
(in which, group address may have mask but the calculation result of the two must
be 224.0.0.0, while source address has no mask), it indicates only (*, *, RP) entry is
deleted.
If group-address is configured to a group address and source-address to 0 (in
which, group address may have mask while source address has no mask), it
indicates only (*, G) entry is deleted.
After this command is executed, not only the multicast route entry is deleted from
PIM, but also the corresponding route entry or forwarding entry in the multicast
kernel routing table and MFC is deleted.
For the related commands, see reset multicast routing-table, reset multicast
forwarding-table, and display pim routing-table.
Example
Clear the route entry with group address of 225.5.4.3 in PIM routing table.
