Containing Service Type and ID
The Containing Service Type is the service type (IES or VPRN) that contains the local SRRP
instance. The Containing Service ID is the service ID of that service. This information is supplied
for troubleshooting purposes only and is not required to be the same on both nodes.
Containing Subscriber IP Interface Name
The containing subscriber IP interface name is the subscriber IP interface name that contains the
SRRP instance and its group IP interface. This information is supplied for troubleshooting
purposes only and is not required to be the same on both nodes.
Subscriber Subnet Information
The subscriber subnet information includes all subscriber subnets backed up by the SRRP
instance. The information for each subnet includes the Owned IP address, the mask and the
gateway IP address. If the received subscriber subnet information does not match the local
subscriber subnet information, an SRRP Subscriber Subnet Mismatch event is generated
describing the SRRP instance ID and the local and remote node IP addresses. Once the subscriber
subnet information matches, an SRRP Subscriber Subnet Mismatch Clear event is generated.
Containing Group IP Interface Information
The containing group IP interface information is the information about the group IP interface that
contains the SRRP instance. The information includes the name of the group IP interface, the list
of all SAPs created on the group IP interface, the administrative and operational state of each SAP
and the MCS key and the peering destination IP address associated with each SAP. To obtain the
MCS information, the SRRP instance queries MCS to determine the peering association of the
SRRP instance and then queries MCS for each SAP on the group IP interface. If the local SRRP
instance is associated with a different MCS peering than any of the SAPs or if one or more SAPs
are not tied to an MCS peering, an SRRP group interface SAP peering mismatch event is
generated detailing the SRRP instance ID, and the group IP interface name.
When receiving the remote containing group IP interface information, the local node compares the
received SAP information with the local group IP interface SAP information. If a local SAP is not
included in the SAP information or a remote SAP is not included in the local group IP interface, an
SRRP Remote SAP mismatch event is generated detailing the SRRP instance ID and the local and
remote group IP interface names. If a received SAP's MCS key does not match a local SAP's MCS
Key, an SRRP SAP MCS key mismatch event is generated detailing the SRRP instance ID, the
local and remote group IP interface names, the SAP-ID and the local and remote MCS keys.
