Brocade Communications Systems FastIron X Series User Manual

Syntax: [no] poison-reverse
To disable poison reverse and enable split horizon on an interface, enter commands such as the following.
device(config)#interface ethernet 1/1/1
device(config-if-e10000-1/1/1)# no ip rip poison-reverse
Syntax: [no] ip rip poison-reverse
To disable split horizon and enable poison reverse on an interface, enter commands such as the following.
device(config)#interface ethernet 1/1/1
device(config-if-e10000-1/1/1)# ip rip poison-reverse
You can
congure the Brocade device to avoid routing loops by advertising local RIP routes with a cost of 16 ("innite" or "unreachable")
when these routes go down.
device(config-rip-router)# poison-local-routes
Syntax: [no] poison-local-routes
Suppressing RIP route advertisement on a VRRP or VRRPE backup
interface
NOTE
This section applies only if you congure the device for Virtual Router Redundancy Protocol (VRRP) or VRRP Extended
(VRRPE).
Normally, a VRRP or VRRPE Backup includes route information for the virtual IP address (the backed up interface) in RIP
advertisements. As a result, other routers receive multiple paths for the backed up interface and might sometimes unsuccessfully use the
path to the Backup rather than the path to the Master.
You can prevent the backups from advertising route information for the backed up interface by enabling suppression of the
advertisements.
To suppress RIP advertisements for the backed up interface, enter the following commands.
device(config)# router rip
device(config-rip-router)# use-vrrp-path
Syntax: [no] use-vrrp-path
The syntax is the same for VRRP and VRRP-E.
Conguring RIP route lters using prex-lists and route maps
You can
congure prex lists to permit or deny specic routes, then apply them globally or to individual interfaces and specify whether
the lists apply to learned routes (in) or advertised routes (out).
You can congure route maps to permit or deny specic routes, then apply a route map to an interface, and specify whether the map
applies to learned routes (in) or advertised routes (out).
NOTE
A route is dened by the destination’s IP address and network
mask.
