Switch(Config-Router-Ospf)#default redistribute tag 20000
18.4.2.2.5 default
redistribute
type
Command: default redistribute type
{ 1 | 2 }
no default redistribute type
Function:
Sets the default route type(s) for exterior routes introduction; the “
no default
redistribute type
” command restores the default setting.
Parameters:
1
and
2
stand for type1 and type2 exterior routes, respectively.
Default:
The system assumes to introduce Type2 exterior routes by default.
Command Mode:
OSPF protocol configuration mode
Usage Guide:
OSPF protocol divides exterior route information into 2 categories by cost selection
method: type1 exterior route and type2 exterior route. The cost of type1 exterior route = advertised
cost of exterior route + cost from a layer 3 switch to the advertising layer 3 switch (AS exterior layer
3 switch). Cost of type2 exterior route = advertised cost of exterior route. If both type1 and type2
exterior routes present, type1 routes take precedence.
Example:
Setting the default exterior route type for OSPF to introduce to type1.
Switch(Config-Router-Ospf)#default redistribute type 1
18.4.2.2.6 ip ospf authentication
Command: ip ospf authentication
{ simple <
auth_key
>| md5 <
auth_key
> <
key_id
>}
no ip ospf authentication
Function:
Configures the authentication method for the interface to accept OSPF packets; the “
no
ip ospf authentication
” command cancels the authentication.
Parameters:
simple
stands for simple authentication;
md5
for MD5 encrypted authentication;
<auth_key>
for authentication key, which should be a string with no blank characters. Up to 8 bytes
in simple authentication and 16 bytes in MD5 authentication are allowed;
<key_id>
is the checksum
word for MD5 authentication, range from 1 to 255.
Default:
Authentication is not required by default for the interface to accept OSPF packets.
Command mode:
Interface Mode
Usage Guide:
The value of key will be written into the OSPF packets to ensure proper OSPF packet
sending/receiving between the layer 3 switch and neighbor layer 3 switches. The partner end must
have the same “
key
” parameters set.
Example:
Configuring MD5 authentication for OSPF interface vlan1 with an authentication
password of “123abc”.
Switch(Config-If-Vlan1)#ip ospf authentication md5 123abc 1
18.4.2.2.7 ip ospf cost
Command: ip ospf cost
<cost>
no ip ospf cost
Function:
Sets the cost for running OSPF on the interface; the “
no ip ospf cost
” command restores
the default setting.
Parameters:
< cost>
is the OSPF cost, ranging from 1 to 65535.
Default:
The default cost for OSPF protocol is 1.
Command mode:
Interface Mode
