Ok, since this is a bundle, we should put restrictions around the max and min

links. Normally this is not a problem, but if you had to guarantee bandwidth

(say 4G, then you might consider having the min links set to 4, and if you

dropped below 4 the interface would go down).

RP/0/RSP0/CPU0:PE2(config-if)#bundle maximum-active links 2

RP/0/RSP0/CPU0:PE2(config-if)#bundle minimum-active links 1

Now let’s take a quick look at our load balancing hash options:

RP/0/RSP0/CPU0:PE2(config-if)#bundle load-balancing hash ?

dst-ip Use the destination IP as the hash function

src-ip Use the source IP as the hash function

So, for this example we will use the src-ip

RP/0/RSP0/CPU0:PE2(config-if)#bundle load-balancing hash src-ip

Now, let’s assign the interfaces to the bundle

RP/0/RSP0/CPU0:PE2(config-if)#int g0/1/0/11

Just like port-channels, the bundle ID should match the interface number you

created. But here we will also look at what bundle options we have:

RP/0/RSP0/CPU0:PE2(config-if)#bundle id 200 mode ?

active Run LACP in active mode over the port.

on Do not run LACP over the port.

passive Run LACP in passive mode over the port.

There are three ways that LACP will link aggregate:

Switch 1

Switch 2

Notes

Active

This is the recommended configuration.

Active

Passive

Link will aggregate once negotiation is done

Aggregation will happen, but not reccomded

We will use LACP in ACTIVE mode as that is what is recommended by Cisco:

RP/0/RSP0/CPU0:PE2(config-if)#bundle id 200 mode active

RP/0/RSP0/CPU0:PE2(config-if)#no shut

And do the same for G0/0/0/11:

RP/0/RSP0/CPU0:PE2(config-if)#int g0/0/0/11

RP/0/RSP0/CPU0:PE2(config-if)#bundle id 200 mode ac

RP/0/RSP0/CPU0:PE2(config-if)#no shut

1 2 ... 13 14 15 16 17 18 19 20 21 22 23 ... 104 105
