Good day!
I'd like to tell you about my configuration example of OSPF between several devices of different vendors. This is first chapter of several parts of OSPF's configuration example
It's not difficult to config, but when i first start to config multivendor devices, i've to TSHOOT some problems. One of the common problem is "mismastched times". D-link devices have timers that greatly differ from other non D-link routers. Pay attention on it, while configuring
Here is example of topology:
Before starting configuration, testing and etc, make sure that you a "configuration and implementation plan" (first chapter in CCNP Route studing). Let's imagine, that we have such plan, then, we can bagin to config our devices
D-link №1 3612:
config ospf ipif "IPIF1" area 0.0.0.0

config ospf ipif "IPIF1"

config ospf ipif "IPIF2" area 0.0.0.0

Notice that D-LINK devices support only area number - XXX.XXX.XXX.XXX.
But area 0 and area 0.0.0.0 - are equal in HEX. That's why following configuration is correct and OSPF neighor were established successfully.
