[nsp] Dynamic load balancing outgoing traffic (unequal paths)

[Noriega, Alejandro]

Thanks for the information Nicolaj !
I read the link and searched about this feature but it doesn't talk much
about how the weighting works. I only found this:
"Use the weighted method of GLBP load balancing when you need unequal
load balancing because routers in the GLBP group have different
forwarding capacities." 

Can I do load balancing of my outgoing traffic with different upstreams
bandwidths with this feature?
This works like eIGRP variance?

Thanks,
Alejandro.

Since you have 3 upstream routers the solutions you suggest could become
very complex, espcialy when you need to coordinate with multiple
providers.

You could use glbp
(http://www.cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature
_guide09186a00801541c8.html ) instead, it supports Weighting. Or use
multiple HSRP groups to "manualy" share the load between your routere.

GLBP is preferred since all you servers will share the same gateway.

Hello guys,
	I'm looking for a scalability solution for dynamic load
balancing the outgoing traffic of my ISP with unequal bandwidth paths. I
have 3 upstream with theirs respective bandwidth: 60, 200 and 120 Mbps
each one in separate routers which are acting like route reflector
clients.

I was thinking in this solutions:
	.- Injecting a default route from the RR-clients to my RR via
eIGRP and using variance (I don't know if this could work).
	.- Reading about BGP Link Bandwidth in this case I may work with
my upstream.
	.- And loosing the dynamic conf: full routing setting different
weights to a set of routes between my upstream.

Any idea?

Thanks in advance.

Regards,
Alejandro.
