3) Enable pim-sm on the interface;
4) Enter pim-sm configuration mode and address range of SSM group address;
5) Configure other functions of pim-sm (optional).
Configuration instances:
switch_config#interface v8
switch_config_v8#ip addr 1.1.1.1 255.255.255.0
switch_config_v8#ip pim-sm
switch_config_v8#exit
switch_config#router pim-sm
switch_config_ps#ssm rang grp_range
switch_config_ps#exit
switch_config#ip access-list standard grp-range
switch_config_std_nacl#permit 233.1.0.0 255.255.0.0
switch_config_std_nacl#
The following configuration does not take the default 232.0.0.0/8 as the group range of SSM, but
233.1.0.0/8. If SSM is canceled, disable ssm related configuration with “no” in the configuration mode of
pim-sm.
75.2.9 Configuring Management Domain sz
In the mechanism of non-management domain, one pim-sm domain only has an exclusive BSR. The
whole network is controlled by the BSR. For better management, the whole pim-sm domain can be divided
into many management domains: each management domain maintains one BSR respectively and serves
the multicast group within a certain range; global domain also maintains one BSR, which serves all left
multicast groups.
In the mechanism of management domain, the boundary of each management domain is consisted
of ZBR and each management domain maintains one BSR, which serves the multicast group of a
certain range. The packets(such as assert message and BSR BootStrap message) of multicast protocol
belonging to this range cannot pass the boundary of the management domain.
In the network which applies the management domain mechanism, select BSR for different multicast
groups from C-BSR. C-RP within the network only forward inform packets to the corresponding BSR and
BSR summarizes these packets on RP-SET and inform all devices within the service management
domain.
For a group, if you want to find its rp, find sz corresponding to this group based on the longest
prefix and sub-mask prevails; and find the corresponding RP-SET in sz according to the prefix and sub-
mask of the group, and then calculate rp.
Steps for configuring management domain:
1 On management boundary device ZBR, configuring the range of local management domain group.
2 In the management domain, enter the configuration of pim-sm:
2.1.1 Configure the group range of standby BSR and keep consistent with the management domain
boundary.
