flameeyes@gentoo.org Quagga is a modern fork of Zebra. Quagga is a routing software package that provides TCP/IP based routing services with routing protocols support such as RIPv1, RIPv2, RIPng, OSPFv2, OSPFv3, BGP-4, and BGP-4+. Quagga also supports special BGP Route Reflector and Route Server behavior. In addition to traditional IPv4 routing protocols, Quagga also supports IPv6 routing protocols. With SNMP daemon which supports SMUX protocol, Quagga provides routing protocol MIBs. Furthermore Quagga supports OSPFAPI, a API interface to the OSPF LSDB. It supports inspection as well as injection of normal and opaque OSPF LSAs. Applications like SRRD - The Service Rounting Redundancy Daemon - can make use of OSPFAPI to inject opaque data into the OSPF routing domain. SRRD, for example, implements a cluster server by using the OSPFAPI to flood service state information into the routing domain. Apply unofficial patch to enable classless prefixes for BGP. Patch and information to be found at http://hasso.linux.ee/doku.php/english:network:quagga Enable multipath routes support for any number of routes Enable OSPFAPI support for client applications accessing the OSPF link state database Enable TCP zserv interface on port 2600 for Zebra/protocol-daemon communication. Unix domain sockets are chosen otherwise. Enable support for sys-libs/readline to provide the Quagga Virtual Terminal Interface Shell (vtysh). Add support for PAM (via sys-libs/pam) to the Quagga Virtual Terminal Interface Shell (vtysh); if the readline USE flag is disabled, this flag is ignored.
