Link aggregation

[Rashmiranjan jena]

Dear Team,

I have two link between my head office to branch office and ospf running for routing. I wan to create a virtual link between them and both two link will work as a single link .

So how will configure for this ?

Hello,

OSPF does equal cost (over a maximum of 4 path) load balancing by default. All you need to do is configure 'ip ospf cost' with the same value on all (4 in your case) participating interfaces.

Hi,

Georg has provided a good sugestion now if you want to create a etherchannel on a router you can configure:

interface Port-channel10
ip address 10.0.0.1 255.255.255.0
ip ospf 1 area 0

interface GigabitEthernet0/0
no ip address
channel-group 10

interface GigabitEthernet1/0
no ip address
channel-group 10

To verify you can use show etherchannel summary
