Q

Configure EIGRP

Is the wildcard mask required? If not, what happens?

A

(config)# router eigrp {asn}
(config-router)# network {ip address} {mask}

Wildcard mask is not required. If no wildcard mask is specified the network is summarized to the nearest major network boundary.

(config)# router eigrp {asn}
(config-router)# network {ip address}

Make sure to include the broadcast keyword to allow broadcasts to be forwarded on the interface! Not needed when mapping the local DLCI to local IP!

20

A

(config)# interface {interface}
(config-if)# no ip address
(config-if)# no frame-relay inverse-arp eigrp {asn}

What does a priority of 0 do?

A

(config)# router ospf {PID}
(config-router)# router-id {router-id}
(config-router)# ip ospf priority {priority}

Priority 0 makes a router ineligable to become either the BDR or the DR

24
Q

Configure an OSPF interface as passive

A

(config)# router ospf {PID}
(config-router)# network {ip address}
(config-router)# passive-interface {interface/default}

25

(config-if)# ip address {ip address} {mask}
(config-if)# ip ospf cost {cost}

26
Q

A

(config)# router ospf 1
(config-router)# auto-cost reference-bandwidth 1000

Note: Units are in Mbps

27
Q

OSPF authentication using MD5

A

(config)# router ospf
(config-router)# area {area} authentication message-digest

(config) # interface {interface}
(config) # ip ospf message-digest-key {key} md5 {password}

Note: Both key number and password must match that of the neighboring router.

28
Q

Propogate default route using OSPF

A

(config)# ip route 0.0.0.0 0.0.0.0 {interface}

The always option will cause the route to propogate a default route even if one is not configured on the router

29
Q

A

(config)# router ospf {PID}
(config-router)# network {ip address}
(config-router)# area {area} stub [no-summary]

A

(config)# router ospf {PID}
(config-router)# router id {RID}
(config-router)# network statements here
(config-router)# area {transit area} virtual link {opposite end rid}

Note: A virtual link has the following requirements:

It must be established between two routers that share a common area and are both ABRs.

One of these two routers must be connected to the backbone.

A virtual link cannot be configured through stub areas.

A 
(config)# interface 
(config-if)# encapsulation frame-relay
(config-if)# ip address {IP} {mask}
(config-if)# ip ospf network broadcast
(config-if)# ip ospf priority {priority}
(config-if)# frame-relay map ip  broadcast

35
Q

Full-mesh Frame Relay: Point-to-Multipoint Networks

A

A 
To Configure OSPFv3:
R2(config)# ipv6 unicast-routing
!
R2(config)# ipv6 router ospf 100
R2(config-rtr)# router-id 10.10.10.1
R2(config-rtr)# area 1 stub no-summary
R2(config-rtr)# exit
!
R2(config)# interface gig1/1
R2(config-if)# ipv6 address 2003:2:1:2::1/64
R2(config-if)# ipv6 ospf 100 area 0
!
R2(config)# interface gig1/2
