Which igp is widely used in industry?
thanks a lot!
"In a purely Cisco environment from my experience it's pretty much 50/50 as to OSPF/EIGRP.
Zeeshan, if you're wondering why a pure Cisco network might run OSPF rather than EIGRP, it also avoids being locked into a proprietary routing protocol. You always have the option of using Brand X.
before the introduction of EIGRP stub feature scalability of EIGRP was an issue.
Limiting the query range is the key point for EIGRP scalability.
I agree with Edison : EIGRP is not regarded as scalable as OSPF in large networks.
Note: Being multivendor ready can be a customer requirement or a wise suggestion
for a consultant.
Hope to help
Think it really depends on the environment.
In a mixed environment (mixed in terms of vendor) then OSPF.
In a purely Cisco environment from my experience it's pretty much 50/50 as to OSPF/EIGRP.
OSPF - open standards.
EIGRP isn't used as much since it's Cisco proprietary and RIP is pretty much dead.
ISIS is used within some large enterprises and service providers but not by much.
I would have to say EIGRP or OSPF. I think EIGRP is more dominating though.
