Re: [HELP] Prepending AS path in Multihomed setup
If this is Internet traffic, then you need to use BGP looking glass to check the BGP table from transit provider perspective. You can use the following link to find most suitable looking glass site.
»Cisco Forum FAQ »How your ISP annouce your subnet via BGP to the Internet: BGP Looking Glass
You also need to work with your ISP (AS 400 and AS 500 administrator) to check their BGP table.
These are preliminary steps to verify each other's BGP table.
You may also need to use the ISP BGP community list to set your and ISP's Local Preferences and AS Path Prepend. |

| So far, our ISP has been ZERO help when contacting them regarding issues such as this, I basically have to nail down the exact problem and tell them what they need to change before they will do anything, thats why I ask, I'm not sure I follow where you are going with this... can you be more specific? |

Morristown, NJ | Pick a looking glass and see what your routes look like there. Do you see two paths? Do you see the prepends on one of them? |
