Detailed Description

Data that applies to a specific peering.

Member Function Documentation

ConfigVar<uint32_t>& BGPPeerData::get_prefix_limit ( ) [inline]
Returns:
the prefix limit.
template<class A >
bool BGPPeerData::multiprotocol ( Safi  safi,
Direction  d = NEGOTIATED 
) const [inline]

Which multiprotocol parameters did we send,receive and negotiate.

Parameters:
safi- Subsequent address family identifier
d- direction, SENT, RECEIVED or NEGOTIATED
Returns:
true if this parameter was set
const AsNum BGPPeerData::my_AS_number ( ) const

Return this routers AS number.

Normally this is simple, but if this router is in a confederation then the AS number depends on the the type of the peering.

void BGPPeerData::save_parameters ( const ParameterList &  parameter_list)

Take the optional parameters out of an open packet and save them in _recv_parameters.

The list is accessible through the parameter_recv_list method.

Member Data Documentation

uint16_t BGPPeerData::_configured_hold_time [private]

Holdtime in seconds.

Value sent in open negotiation.
