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.

Remote Redundant IP Interface Mismatch

If the group IP remote redundant IP interface address space does not exist, is not within the local

routing context for the SRRP instances group IP interface or is not on a redundant IP interface, the

local node sends redundant IP interface unavailable to prevent the remote neighbor from using its

redundant IP interface. An SRRP redundant IP interface mismatch event is generated for the SRRP

instance detailing the SRRP instance, the local and remote system IP addresses, the local and

remote group IP interface names and the local and remote redundant IP interface names and IP

addresses and masks. The local redundant IP interface may still be used if the remote node is not

sending redundant IP interface unavailable.
