Join Lazaro Diaz for an in-depth discussion in this video Understanding the election process, part of Advanced Cisco Routing: RIPv2, EIGRP, and OSPF.
- Alright, one of the things…that we previously mentioned…when configuring OSPF,…and we actually looked at it,…was the interface or several interfaces…if you add zero, zero or serial,…that we saw that it was a DR.…A DR stands for a Designated Router…and a BDR stands for…a Backup Designated Router.…And I stated that that only happens…in a multiaccess environment.…For those of you who…are taking certifications especially,…this is very, very important…because you're going to get…a scenario similar to this.…
Now what's going to happen here,…OSPF is going to run an election…and it's going to decide…who is going to be a Designated Router…based on the highest IP address…on any physical interface…and what we're going to do…and I'm going to show you now…starting from Router1 is we're going…to put the IP addresses but we're…going to do it in a certain fashion.…I'm going to go from Router1 to Router2…to Router3 and then to Router4.…Once I put the IP addresses on there,…then we'll go ahead and configure OSPF…and remember what I stated,…
