Front 1

HSRP provides this to clients

Back 1

Virtual MAC address and IP address

Front 2

HSRP priority dictates the..

Back 2

selection of the Active router (highest)

Front 3

Default HSRP priority value

Back 3

100

Front 4

HSRP exchanges UDP based hellos to multicast address...

Back 4

224.0.0.2:1985

Front 5

HSRP Standby Address reported as duplicate

Back 5

Does not necessarily indicate problem with HSRP (usually STP, etherchannel, or dup frame issue)

Front 6

HSRP State flapping

Back 6

HSRP not receiving hellos -physical layer problem

Front 7

HSRP fails to recognize peer

Back 7

physical layer problem, or issue with VTP

Front 8

State change with error (mac flap)

Back 8

If virtual mac - HSRP Issue, if not STP or physical layer

Front 9

State change with error (addr flap)

Back 9

physical issue more likely

Front 10

state change with error (moveoverflow)

Back 10

if issue is HSRP address, could be two active routers

Front 11

state changes on multicast stub

Back 11

common cause deals with non-RPF traffic that non-designated router sees

an access-list on the non-DR is needed

Front 12

Asymmetric routing

Back 12

can result in excessive mac flooding

adjust mac aging time or arp timeout or both

Front 13

HSRP virtual IP reported as different

Back 13

intervlan leakage because of bridging loops in the switch

Front 14

HSRP causes mac violation with port sec

Back 14

force the device to use the burned-in mac instead of virtual

Front 15

Interface hardware cannot support multiple groups

Back 15

force the device to use the burned-in mac instead of the virtual
