OSPF Link-state IGP with fast convergence and support for large
networks
OSPF adjacency phases:
Down – Init – 2way - ExStart – Exchange – Loading – Full
OSFP elects DR and BDR routers on broadcast medium like Ethernet

BGP BGP is exterior routing protocol used to connected different
autonomous systems. iBGP and eBGP BGP configuration requires
neighbour IP address AS number of the neighbour local AS number.

BGP route selection Local preference AS Path Origin MED eBGP over iBGP Best exit from AS For eBGP prefer the current active route RID, cluster lenght, peer ID
