must be specified for anti-spoof mac, and anti-spoof ip-mac and arp-reply-agent. Multiple static
hosts may be configured with the same MAC address given that each definition is distinguished
by a unique IP address.
Every static host definition must have at least one address defined, IP or MAC.
identification profile to be associated with the static subscriber host. The subscriber identification
profile is configured in the config>subscr-mgmt>sub-ident-policy context. The subscriber
information is used by the VPRN SAP arp-reply-agent to determine the proper handling of
received ARP requests from subscribers.
• For VPRN SAPs with
static subscriber host's sub-ident-string is used to determine whether an ARP request
received on the SAP is sourced from a host belonging to the same subscriber as the
destination host. When both the destination and source hosts from the ARP request are
known on the SAP and the subscriber identifications do not match, the ARP request may be
forwarded to the rest of the VPRN destinations.
If the static subscriber host's sub-ident string is not defined, the host is not considered to
belong to the same subscriber as another host on the SAP.
If source or destination host is unknown, the hosts are not considered to belong to the same
subscriber. ARP messages from unknown hosts are subject to anti-spoof filtering rules
applied at the SAP.
If sub-ident is not enabled on the SAP arp-reply-agent, subscriber identification matching is
not performed on ARP requests received on the SAP.
ARP requests are never forwarded back to the same SAP or within the receiving SAP's Split
Horizon Group.
