New Features Page 10 of 97
BGP Network Route Tables
The BGP Network Route table provides a mechanism to make BGP initiate the
advertisement of a route without the need to import it into BGP from another routing
protocol. In conjunction with the IGP Synchronization flag, it can conditionally
advertise routes only if they exist in the IGP table. This provides more granular con-
trol than in previous releases.
BGP Multi-path Load Balancing
This feature will allow Vanguard Networks customers to support architectures where
the customer site is connected to multiple BGP peers. With multipath load balanc-
ing, multiple BGP connections can share the packet traffic.
Same AS in AS-Path optional override
The Same AS in AS-Path optional override feature provides better support for MPLS
VPNs. Since BGP AS is now geographically dispersed, the BGP AS is no longer
contiguous. BGP normally considers an error. Without this feature, the MPLS net-
work must override the BGP AS_PATH in order to create an MPLS VPN.
In-Band DTMF packet signaling RFC 2833
This feature will allow In-Band signaling to be used with Dual-tone multi-frequency
(DTMF). This will allow a PBX and/or Switch to send DTMF information to a SIP
UA (User Agent) via in-band messages.
