[c-nsp] Design issue for customer with dual MPLS links

[Arie Vayner (avayner)]

Jack,

I think you should take a look at PfR (used to be called OER):

rt_diversity/Transport_Diversity_PfR.html
http://www.cisco.com/en/US/products/ps8787/products_ios_protocol_option_
home.html

Hi Guys,

This is a paticular design issue I'm facing with customer where I have a
lot
of constrainits .

Topology


MPLS CLOUD (ISP1)
MPLS CLOUD (ISP2)
|
|
|
|
|
|
CE1
CE2
|
                    |
|--------------------------------PIX525
(CLUSTER)---------------------------------
                                    |
                                    |
                                    |
                                  LAN ( 6509 catalyst switch - runnning
HSRP)


Issue - I want  to go out via ISP1 and come back via ISP1 ......Backup
is
CE2

When traffic reaches PIX cluster how will it decide whether ISP1 is UP
and
traffic is not blackholed......How will PIX cluster decide to FWD
traffic to
ISP2.

Now for this solution , constraints are -

1) I cant run HSRP on CE1 and CE2
2) Cant run run dynamic routing on PIX
3) IP SLA also can't also be used on PIX cluster

Regards
