Архитектура Quagga Для начала несколько слов об общей архитектуре Quagga. So BGP can simply be configured as usual and the traffic is distributed over the ports using the ECMP algorithm. It appears that running Quagga on both end points, speaking BGP to each other, will allow ECMP over the 6-12 IPsec tunnels. An OF-DPA L3 ECMP Group entry can be specified as a routing target instead of an OF-DPA L3 Unicast Group entry. Toto howto bylo psáno pro routovací démon zebra, ale protože quagga je fork zebry, je toto howto použitelné i s quaggou. ECMP at the routers spreads packets across the muxes, which direct traffic to servers; finally the servers respond directly to clients. Rekhter & T. Quagga contains a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on a targeted system. Rich feature set provided by the Linux standard IP stack without vendor-specific changes. Cisco Router. Use whatevere your comfortable with. BGP unnumbered interfaces are particularly useful in deployments where IPv4 prefixes are advertised through BGP over a section without any IPv4 address configuration on links.
