SRRP State

currently exist)
Page 870
lists the SRRP's state effect on subscriber hosts associated with group IP interfaces.
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
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
• Responds to 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).
Remote Proxy
ARP Enabled
• Responds to ARP
for all reachable
remote IP hosts.
• Responds to ARP
for all reachable
remote IP hosts
(hardware address
= SRRP gateway
MAC address,
source MAC =
group IP interface
native MAC).

Subscriber Host
Routing
• All routing out the
group IP interface
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
group IP interface
use the native group
IP interface MAC
address.
• Subscriber hosts
mapped to the
redundant IP
interface are
remapped to the
group IP interface.
• Will not accept
packets destined to
the SRRP gateway
MAC received on
the group IP
interface.
