Hi Guys,

We have a customer who has 2 CPE routers. We have 2 uplinks, the first one
attached to the first router CPE1, the second one attached to the second
router CPE2.

We have ebgp configured with 2 different PE's and IBGP between the CPE's.
HSRP is configured on the LAN. Unfortunately, we can't use GLBP because
there is a L3 switch behind the CPE's.

How can we achieve the loadbalancing between the 2 links ?

PE1            PE2
  |                |
  |                |
ebgp           ebgp
  |                |
  |                |
 CE1 --Ibgp--- CE2


Thanks and Best Regards,
