If you configure the redistribution of OSPF into BGP without keywords, only OSPF intra-area

and inter-area routes are redistributed into BGP, by default. You can use the internal keyword

along with the redistribute command under router bgp to redistribute OSPF intra- and inter-area

routes.

Use the external keyword along with the redistribute command under router bgp to redistribute

OSPF external routes into BGP.

-> In order to redistribute all OSPF routes into BGP, we must use both internal and external

keywords. The full command would be (suppose we are using OSPF 1):

redistribute ospf 1 match internal external

Note: The configuration shows match internal external 1 external 2. This is normal because

OSPF automatically appends “external 1 external 2” in the configuration. In other words,

keyword external = external 1 external 2. External 1 = O E1 and External 2 = O E2.

SNMP notifications can be sent as traps or inform requests. Traps are unreliable because the receiver does not send acknowledgments when this device receives traps.”Send reliable and encrypted notifications for any events” so it is SNMP notifications. For encryption we need to configure “priv”.

EIGRP does not have process ID as it uses Autonomous System (AS) numbers only.

This is not an authentication problem or we would see this error from the debug:

EIGRP: Ethernet0/0: ignored packet from 10.1.1.3, opcode = 1 (missing authentication or key-chain missing)

If the AS numbers between two routers are different then the neighbor relationship cannot be formed.
