18.4.2.2.5default 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.
18.4.2.2.6ip 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”.
18.4.2.2.7ip 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
