| in the ospf area network dr and bdr selection procedure occur
let there are 4 router in that n/w r1 have the higher priority
then r2 and r2 have higher priority then r3 and so on
like that
r1>r2>r3>r4
now as we know that selection of dr and bdr based upon the
router priority so in this case r1 will be dr and r2 will be
bdr
now my question is that if i am going to implement 5th
router which have greater priority then r1 then will it become dr atomically
remember that i am not going change my 5 or 1st router property

| Hi, All
I am configuring EIGRP in Packet tracer, after configuring
all the things it is not working but in one condition it is
working fine if i am putting all my router and network
withing one network subnets e.g. 172.16.0.0 or 10.0.0.0 but
whenever i am puting different network subnets e.g. in one
network it is RA(config-if)#=ip address 10.0.0.1, and in
fa0/0= 192.168.1.10 and in RB(config-if)#10.0.0.2 (s1/0) and
in S1/1 11.0.0.1 and in fa 0/0 192.168.100.1 ,where as in
third router RC(config-if)#=ip address 11.0.0.2 and in fa
0/0 172.16.1.10 and after configuring all this serial is
showing up and protocol showing up but eigrp process not
taking place after adding eigrp configuration, i tried with
"no auto-summary" command but not working.. Suggest me where
i missing something? can mail me at : gtech.innovator@gmail.com | | 18 |
