Link aggregation on Redback SMS routers

Marcel — Tue, 07 Apr 2009 08:27:54 +0000

To configure link aggregation on Redback SMS routers you need to do the following.

Create the link group interface and assign an IP address to it

[local]Redback(config)#context local
[local]Redback(config-ctx)#interface AMS-IX
[local]Redback(config-if)#ip address 195.69.x.x/23
[local]Redback(config-if)#exit

Create the link group and bind it to its interface

[local]Redback(config)#link-group AMS-IX ether
[local]Redback(config-link-group)#bind interface AMS-IX local

Configure an ethernet port and add it to the link group

[local]Redback(config-config)#port ethernet 1/1
[local]Redback(config-port)#no shutdown
[local]Redback(config-port)#link-group AMS-IX
[local]Redback(config-port)#exit

Configure another ehternet port and add it to the link group

[local]Redback(config-config)#port ethernet 1/2
[local]Redback(config-port)#no shutdown
[local]Redback(config-port)#link-group AMS-IX
[local]Redback(config-port)#exit

To match the AMS-IX arp timeout (4 hours) you need to configure this under the interface

[local]Redback(config)#context local
[local]Redback(config-ctx)#int AMS-IX
[local]Redback(config-if)#ip arp timeout 14400
[local]Redback(config-port)#exit

Also, you can set your aggregated min-links to a value that will cause the bundle to drop in the event that your links can no longer support the amount of traffic you move trough the link-group.Thus, 2-port aggregated link, pushing 1.2 Gbps sustained across, drop bundle if n == 1;

[local]Redback(config)#link-group AMS-IX ether
[local]Redback(config-link-group)#minimum-links 2
[local]Redback(config-link-group)#exit

This config is made to interconnect with an aggregated link towards the AMS-IX. For other Link aggregation interconnects you need to make changes towards this config.

Today I added the wptouch plugin to the apple.t-b.nl site so it is more readable on the iphone. Some people were complaining about it. So i hope i made them happy. I’m looking into some other plugins at the moment to make the site load a littlebit faster.

I like to read rumors about new Apple. The only problem is that their are to many sites that publish rumors about Apple. So i decided to aggregate some of these sites (Macrumors / TUAW / Appleinsider) into WordPress.
Now i only have to read one site to find out if their are new rumors / publications. So if you think ( yeah some people are reading my blog) it is useful leave a comment. The site need some more changes and a decent name. For now you can find it here

People stop bugging me for Juniper configs. I’m not your personal create my first Juniper
config engine. Everything on my blog you may / can use if you like. I’m not going
to write your configs. Really how hard can it be to design / write your own configs.

So please stop asking me for complete configs !!!! Get a J Course or Google a bit
