This is from a router acting as client ( ip gdp irdp ) ,

the router picks the lower preference gateway .

In archive , people said win98/2000 will pick the higher preference .

What's the standard answer then ?

04:58:46: GDPclient: 135.4.30.18 via IRDP, interval 12, exp 0x112002B, priority 3

04:58:47: GDPclient: 135.4.30.22 via IRDP, interval 14, exp 0x112147A, priority 2

04:58:53: GDPclient: picked new default router 135.4.30.22

r6-labr3#

04:58:59: GDPclient: 135.4.30.18 via IRDP, interval 12, exp 0x1123410, priority

3

04:59:01: GDPclient: 135.4.30.22 via IRDP, interval 14, exp 0x1124B6D, priority

preference number

(Optional) Preference value. The allowed range is -231 to 231. The default is 0. A higher value increases the preference level of the router. You can modify a particular router so that it will be the preferred router to which other routers will home.

but in the sample config :! enable irdp on interface Ethernet 0 interface ethernet 0
ip irdp
! send IRDP advertisements to the multicast address ip irdp multicast
! increase router preference from 100 to 50 ip irdp preference 50
! set maximum time between advertisements to 400 secs ip irdp maxadvertinterval 400
! set minimum time between advertisements to 100 secs ip irdp minadvertinterval 100
! advertisements are good for 6000 seconds ip irdp holdtime 6000
! proxy-advertise 131.108.14.5 with default router preference ip irdp address 131.108.14.5
! proxy-advertise 131.108.14.6 with preference of 50 ip irdp address 131.108.14.6 50 WHAT IS INCREASE PREFERENCE FROM 100 TO 50 ?! any idea ?thanks !
