Hi Giuseppe,

My main concern here my 2 GSR link is eating up 800Mbps plus of traffic, thats why im finding a way at least balance it on 2 GE. Do you think aggregating this will help? coz i think the throughput per port is 3/2.5Gps , is this correct?

Thanks.

Hello Jeff,

you can use two GE full rate of 3.

As I have written before I wouldn't aggregate the two GE in a bundle but I would use L3 load balancing.

Hope to help

Hi Guiseppe,

2GE at full rate 3Gig is that what you mean? If i use L3 load balancing what would it be? How is this using routing protocols?

Thanks.

jeff

Hello Jeff,

2 GE full rate = 2 GE ports that can send and receive 1Gbps at the same time.

I simply mean that the two GE have each its own ip address and you use OSPF or other IGP to perform load balancing over them.

For example we did so in a mobile operator network using two GE of 3 with no problems.

Hope to help

Hi Giuseppe,

The 2 GSR links uses IBGP , how will be the config then if i use two ip address per interface.

Thanks.

jeff

Hello Jeff,

use iBGP sessions on loopback interfaces advertised on the IGP you use

then thanks to recursion the BGP next hop is resolved on the two parallel links and you get load balancing CEF flow based.

Hope to help
