d. Configure OSPF packet sending timer parameter (timer of broadcast interface sending HELLO packet to poll, timer of neighboring layer 3 switch invalid timeout, timer of LSA transmission delay and timer of LSA retransmission.

Command

Explanation

 

 

 

 

Interface Mode

 

 

 

 

 

 

ip ospf hello-interval <time>

Sets interval for sending HELLO packets; the “no

ip ospf hello-interval

command restores the

no ip ospf hello-interval

default setting.

 

 

 

 

 

 

 

 

 

ip ospf dead-interval <time >

Sets the interval before regarding a neighbor layer

3 switch invalid; the “no ip ospf dead-interval

no ip ospf dead-interval

command restores the default setting.

 

 

 

 

 

 

 

ip ospf transmit-delay <time>

Sets the

delay

time

before

sending link-state

broadcast;

the

no

ip

ospf

transmit-delay

no ip ospf transmit-delay

command restores the default setting.

 

ip ospf retransmit <time>

Sets the interval for retransmission of link-state

advertisement among neighbor layer 3 switches;

no ip ospf retransmit

the “no ip ospf retransmit” command restores the

 

default setting.

 

 

 

 

(2)Configure OSPF route introduction parameters

a. Configure default parameters (default type, default tag value, default cost, default interval and default number uplimit)

Command

 

Explanation

 

 

 

 

 

 

OSPF protocol configuration mode

 

 

 

 

 

 

 

 

 

 

 

default redistribute type { 1 2 }

 

Sets

the

default

route weight for route

to be

 

introduced;

the

no default-metric command

no default redistribute type

 

 

restores the default setting.

 

 

 

 

 

 

 

 

default redistribute tag <tag>

 

Sets the default tag value for introducing external

 

routes;

the

no

default

redistribute

tag

no default redistribute tag

 

 

command cancels the tag value setting.

 

 

 

 

 

 

Sets the default cost for introducing external

default redistribute cost <cost>

 

routes; the “no default redistribute cost

no default redistribute cost

 

command cancels the cost for introducing external

 

 

routes. .

 

 

 

 

 

 

 

default redistribute interval <time>

 

Sets

the

interval

for

introducing external

routes;

 

the “no default redistribute interval” command

no default redistribute interval

 

 

restores the default setting.

 

 

 

 

 

 

 

 

default redistribute limit <routes>

 

Sets

the

maximum

for

external

routes

 

introduction; the “no default redistribute limit

no default redistribute limit

 

 

command restores the default setting.

 

 

 

 

b. Configure the routes of the other protocols to introduce to OSPF.

 

 

 

Command

 

 

Explanation

 

 

 

 

 

OSPF protocol configuration mode

 

 

 

 

 

 

 

 

 

 

redistribute ospfase { bgp connected

 

Introduces BGP routes, direct routes, static

 

routes and RIP routes as external routing

static rip} [ type { 1 2 } ] [ tag <tag> ]

 

information;

the “no

redistribute ospfase

[ metric <cost_value> ]

 

 

{ bgp connected static rip }” command

no redistribute ospfase { bgp connected

 

 

cancels

the

introduction

of external routing

static rip }

 

 

information.
