View definitionBGP Community
A BGP community is an optional route tag used to apply routing policy across routers and networks.
View definitionBGP Extended Community
An extended BGP community carries structured routing policy information, including route targets used in VPN routing.
View definitionBGP Graceful Restart
BGP Graceful Restart helps preserve forwarding during a temporary control-plane restart when supported by peers.
View definitionBGP Large Community

View definitionBGP Route Reflector
a BGP router that reflects iBGP routes between clients to reduce full-mesh requirements
View definitionBPDU Guard
A STP protection that disables a port of access receiving a BPDU
View definitionBroadcast Domain
