VPRN Service Configuration Commands
Page 996 7750 SR OS Services Guide
one or more subscriber subnets do not have an SRRP gateway IP address defined. Creating a new
subscriber subnet without an SRRP gateway IP address defined will fail when the subscriber subnet is
associated with a group IP interface with an active SRRP instance. Once SRRP is enabled on a group
interface, the SRRP instance will manage the ARP response and routing behavior for all subscriber
hosts reachable through the group IP interface.
The no form of the command removes the address from a subscriber subnet. The address command
for the specific subscriber subnet must be executed without the gw-address parameter. To succeed, all
SRRP instances associated with the subscriber subnet must removed or shutdown.
Parameters ip-address/mask | ip-address netmask — Specifies the address space associated with the subscriber
subnet
gw-ip-address ip-address — Specifies a separate IP address within the subnet for SRRP routing
purposes. This parameter must be followed by a valid IP interface that exists within the
subscriber subnet created by the address command. The defined gateway IP address cannot
currently exist as a subscriber host (static or dynamic). If the defined ip-address already exists as
a subscriber host address, the address command will fail. The specified ip-address must be
unique within the system.
The gw-address parameter may be specified at anytime. If the subscriber subnet was created
previously, executing the address command with a gw-address parameter will simply add the
SRRP gateway IP address to the existing subnet.
If the address command is executed without the gw-address parameter when the subscriber
subnet is associated with an active SRRP instance, the address will fail. If the SRRP instance is
inactive or removed, executing the address command without the gw-address parameter will
remove the SRRP gateway IP address from the specified subscriber subnet.
If the address command is executed with a new gw-address, all SRRP instances currently
associated with the specified subscriber subnet will be updated with the new SRRP gateway IP
address.
group-interface
Syntax [no] group-interface ip-int-name
Context config>service>vprn>sub-if
config>service>vprn>subscriber-interface
Description This command enables the context to configure a group interface. A group interface is an interface
that may contain one or more SAPs. This interface is used in triple-play services where multiple SAPs
are part of the same subnet.
Default none
Parameters ip-int-name — Configures the interface group name. If the string contains special characters (#, $,
spaces, etc.), the entire string must be enclosed within double quotes.
