ssm-translate
Syntax igmp
Context config>service>vprn>igmp
Description This command enables the context to configure group ranges which are translated to SSM (S,G)
entries. If the static entry needs to be created, it has to be translated from a IGMPv1 IGMPv2 request
to a Source Specific Multicast (SSM) join. An SSM translate source can only be added if the starg
command is not enabled. An error message is generated if you try to configure the source command
with starg command enabled.
grp-range
Syntax [no] grp-range start end
Context config>service>vprn>igmp>ssm-translate
Description This command is used to configure group ranges which are translated to SSM (S,G) entries.
Parameters start — An IP address that specifies the start of the group range.
end — An IP address that specifies the end of the group range. This value should always be greater
than or equal to the value of the start value.
source
Syntax [no] source ip-address
Context config>service>vprn>igmp>ssm-translate>grp-range
Description This command specifies the source IP address for the group range. Whenever a (*,G) report is
received in the range specified by grp-range start and end parameters, it is translated to an (S,G)
report with the value of this object as the source address.
Parameters ip-address — Specifies the IP address that will be sending data.
maximum-routes
Syntax maximum-routes number [log-only] [threshold percentage]
no maximum-routes
Context config>service>vprn
Description This command specifies the maximum number of routes that can be held within a VPN routing/
forwarding (VRF) context.
If the log-only parameter is not specified and the maximum-routes value is set below the existing
number of routes in a VRF, then the offending RIP peer (if applicable) is brought down (but the
VPRN instance remains up). BGP peering will remain up but the exceeding BGP routes will not be
added to the VRF.
