HP J9726A User Manual

Example 34 Output for the show IP rip peer < ip-addr > command
HP Switch# show ip rip peer 100.0.1.100
RIP peer information for 100.0.1.100
IP Address : 100.1.0.100
Bad routes : 0
Last update timeticks : 2
This display lists information in the fields described above (IP address, Bad routes, Last update
timeticks.)
Viewing RIP redistribution information
To display RIP redistribution information, enter the show ip rip redistribute command at
any context level:
Example 35 Output for the show IP rip redistribute command
HP Switch# show ip rip redistribute
RIP redistributing
Route type Status
---------- ------
connected enabled
static disabled
RIP automatically redistributes connected routes that are configured on interfaces that are running
RIP and all routes that are learned via RIP. The router rip redistribute command, described
in “Configuring for redistribution” (page 55), configures the routing switch to cause RIP to advertise
connected routes that are not running RIP or static routes. The display shows whether RIP
redistribution is enabled or disabled for connected or static routes.
Viewing RIP redistribution filter (restrict) information
To display RIP restrict filter information, enter the show ip rip restrict command at any
context level:
Example 36 Output for the show IP rip restrict command
HP Switch# show ip rip restrict
RIP restrict list
IP Address Mask
--------------- ------------
The display shows if any routes identified by the IP Address and Mask fields are being restricted
from redistribution. The restrict filters are configured by the router rip restrict command
(see “Configuring for redistribution” (page 55)).
Configuring IRDP
The ICMP Router Discovery Protocol (IRDP) is used by HP routing switches to advertise the IP
addresses of their router interfaces to directly attached hosts. IRDP is disabled by default. You can
enable the feature on a global basis or on an individual VLAN interface basis.
When IRDP is enabled, the routing switch periodically sends Router Advertisement messages out
the IP interfaces on which the feature is enabled. The messages advertise the routing switch's IP
