What can go wrong? Routing Design Errors (cont)
Route Reflector Disadvantage (4):
- Migration from Route Reflector to “correct” routing configuration is highly non-trivial
- ISP router is in IXP’s ASN
- Need to move ISP router from IXP’s ASN to the ISP’s ASN
- Need to reconfigure BGP on ISP router, add to ISP’s IGP and iBGP mesh, and set up eBGP with IXP participants and/or the IXP Route Server
