This feature provides the support of SDP administrative groups, referred to as SDP admin groups. SDP admin groups provide a way for services using a PW template to automatically include or exclude specific provisioned SDPs. SDPs sharing a specific characteristic or attribute can be made members of the same admin group.
The user first creates the admin groups that are to be used by SDPs on this node:
config>service>sdp-group>group-name group-name value group-value create
A maximum of 32 admin groups can be created. The no option is only allowed if the group name is not referenced in a PW template or SDP.
The group value ranges from zero (0) to 31. It is uniquely associated with the group name at creation time. If the user attempts to configure another group name for a group value that is already assigned to an existing group name, the SDP admin group creation is failed. The same happens if the user attempts to configure an SDP admin group with a new name but associates it to a group value already assigned to an existing group name.
Next, the user configures the SDP membership in admin groups:
config>service>sdp>sdp-group group-name
The user can enter a maximum of one (1) admin group name per command execution. The user can execute the command multiple times to add membership to more than one admin group. The admin group name must have been configured or the command fails. Admin groups are supported on an SDP of type MPLS (BGP/RSVP/LDP). They are also supported on an SDP with the mixed-lsp-mode option enabled.
The user then selects which admin groups to include or exclude in a specific PW template:
config>service>pw-template>sdp-include group-name
config>service>pw-template>sdp-exclude group-name
The admin group name must have been configured or the command is failed. The user can execute the command multiple times to include or exclude more than one admin group. The sdp-include and sdp-exclude commands can only be used with the use-provisioned-sdp option. If the same group name is included and excluded within the same PW template, only the exclude option is enforced.
Any changes made to the admin group sdp-include and sdp-exclude constraints are reflected only in existing spoke-SDPs after the following command has been executed:
tools>perform>service>eval-pw-template>allow-service-impact
When the service is bound to the PW template, the SDP selection rules enforce the admin group constraints specified in the sdp-include and sdp-excludecommands.
config>service>vpls>bgp>pw-template-binding policy-id
config>service>epipe>spoke-sdp-fec>pw-template-bind policy-id
The group value is used to uniquely identify an SDP admin group throughout the network in the 5620 SAM. The node sends both the group name and value to 5620 SAM, or other SNMP device, at the creation of the SDP admin group. In all other operations in the node, such as adding an SDP to an admin group or including/excluding an SDP admin group in a service context, only the group name is sent to the 5620 SAM or the SNMP device.
SDP admin groups can be enabled on all 7210 services that make use of the PW template (that is, BGP-AD VPLS service, BGP-VPLS service, BGP-VPWS and FEC129 VLL service).
