lists the SRRP's state effect on subscriber hosts associated with group IP interfaces.
ARP
• Responds to ARP • Responds to ARP
for all owned
subscriber subnet
IP addresses.
• Will not respond to
ARP for subscriber
subnet SRRP
gateway IP
addresses.
• All ARP responses
will contain the
native MAC of the
group IP interface
(not the SRRP
gateway MAC).
• Responds to ARP • Responds to ARP
for all owned
subscriber subnet
IP addresses
(hardware address
and source MAC =
group IP interface
native MAC).
• Responds to ARP
for subscriber
subnet SRRP
gateway IP
addresses(hardware
address = SRRP
gateway IP
address,source
MAC = group IP
interface native
MAC).
Local Proxy ARP
Enabled
• Respondsto ARP
for all subscriber
hosts on the
subscriber subnet.
• Responds to ARP
for all subscriber
hosts on the
subscriber subnet
(hardware address
= SRRP gateway
MAC address,
source MAC =
group IP interface
native MAC).
Internet Enhanced Services
Remote Proxy Subscriber Host
ARP Enabled
• All routing out the
for all reachable group IP interface
remote IP hosts. will use the native
group IP interface
MAC address.
• The group IP
interface redundant
IP interface will not
be used.
• Will not accept
packets destined to
the SRRP gateway
MAC received on
the group IP
interface.
• All routing out the
for all reachable group IP interface
remote IP hosts use the native group

= SRRP gateway address.
MAC address, • Subscriber hosts

mapped to the
group IP interface redundant IP
native MAC). interface are
remapped to the
group IP interface.
• Will not accept
packets destined to
the SRRP gateway
MAC received on
the group IP
interface.
