Enable Pim-Ssm; Use Pim-Ssm With Igmp Version 2 Hosts - Dell Force10 C150 Configuration Manual

Enable PIM-SSM

To enable PIM-SSM:
Step Task
1 Create an ACL that uses permit rules to specify what range of
addresses should use SSM. You must at least include one
permit 232.0.0.0/8
rule,
PIM-SSM.
2 Enter the command
you created.
Display address ranges in the PIM-SSM range using the command
EXEC Privilege mode.

Use PIM-SSM with IGMP version 2 Hosts

PIM-SSM requires receivers that support IGMP version 3. You can employ PIM-SSM even when receivers
support only IGMP version 1 or version 2 by translating (*,G) entries to (S,G) entries.
Translate (*,G) entries to (S,G) entries using the command
CONFIGURATION mode. In a standard access list, specify the groups or the group ranges that you want
to map to a source. Then, specify the multicast source.
• When a SSM map is in place and FTOS cannot find any matching access lists for a group, it continues
to create (*,G) entries because there is an implicit deny for unspecified groups in the ACL.
• When you remove the mapping configuration, FTOS removes the corresponding (S,G) states that it
created and reestablishes the original (*,G) states.
• You may enter multiple
ssm-map
780 | PIM Source-Specific Mode
, which is the default range for
ip pim ssm-range
and specify the ACL
/ MaskLen
/ 32
ssm-map
commands for different access lists. You may also enter multiple
commands for the same access list, as long as they use different source addresses.
