In addition, it is possible to affect the LOCAL-PREF settings within the sunrise network. Use these with care, as the results can be serious.
 

default customer route local pref 100

 
6730:0001 set local pref to 95
6730:0002 set local pref to 94
 
default swiss peer route local pref 90
 
6730:0003 set local pref to 85
6730:0004 set local pref to 84
 
default international peer route local pref 80
 
6730:0005 set local pref to 75
6730:0006 set local pref to 74
 
default upstream route local pref 70
 
6730:0007 set local pref to 65
6730:0008 set local pref to 64
 


 

To implement these BGP communities on your link to sunrise, use a config similar to the following
 
neighbor x.x.x.x remote-as 6730
neighbor x.x.x.x description sunrise
neighbor x.x.x.x send-community
neighbor x.x.x.x route-map to_sunrise out
 

route-map to_sunrise permit 10
set community 6730:aaaa
 


 

The following BGP community strings may be used to determine the source of a route

Applying BGP Community string with sample configuration

1. Get the latest BGP community string from your ISP/upstream provider or check new.CiscoNET.com web site.

2. Pick the best BGP community string for your traffic shaping plan (mainly incoming traffic). Most of ISPs are providing BGP community string with local preference and AS prepending option. Cannot tell which one is better than the other. It will depend on your global traffic shaping plan.

3. Follow the below commands ( Cisco only )

The below Sample configuration will tag the 10.0.0.0/24 route with [ISP AS]:120 or [ISP AS]:3 and will not tag any other routes.

router#config t
router(config)#ip bgp-community new-format
router(config)#access-list 10 permit 10.0.0.0 0.0.0.255
router(config)#access-list 10 deny any

router(config)#route-map [to-ISP] permit 10
router(config-route-map)#match ip address 10
router(config-route-map)#set community [ISP AS]:120 <---- using Local Preference

or

router(config-route-map)#set community [ISP AS]:3 <------- using AS prepending
router(config-route-map)#route-map [to-ISP] permit 20
router(config-route-map)#exit

router(config)#router bgp [xxxx] <------------------------------- xxxx = customer's ASN
router(config-router)#neighbor x.x.x.x send-community
router(config-router)#neighbor x.x.x.x route-map [to-ISP] out
router(config-router)#exit
router(config)#exit
router#copy running-config startup-config
 

4. And then, go to www.CiscoNET.com and pick one of route server on the map to see your announcement. If you are using AS prepending option, you will see your AS prepends on route servers. Sometime you might not see your route with particular ISP path.
In most of case it might not be any routing problem, just the route path was dropped at somewhere by BGP best path selection scheme. Try Oregon route server, if you can see your route. The Oregon route server is providing many possible and available paths between BGP speakers and neighbors.
If you don't see your route on there? check other route servers and also check your
BGP configuration. You might need to contact your upstream provider to check what they are learning BGP route from you.
