First, the development process of routing protocols and classification
Distance vector routing protocol - listen "rumors", uses a hop count as the metric, up to 16 (0-15) Jump: RIP
Link-state routing protocol - the "map" routing protocols: OSPF, IS-IS
Path Vector Protocol: BGP-- border gateway routing protocol between routing domains (AS-AS) to exchange network reachability information.
Hybrid routing protocols: EIGRP.
There are class routing: differentiated network class in the strict sense, when routing updates do not carry subnet mask;
Classless routing: carry the mask when routing updates;
Two, RIPV1 and V2 difference
Three, RIP route summary (usually in the export route) (eg: 172.16.12.0,172.16.13.0,172.16.14.0,172.16.15.0):
Are summarized in the interface to make , to select a location summary route;
Network part: the same is to write a few a few;
Mask portions: writing a same, different write 0;
172.16.12.0--172.16.00001100.0
172.16.13.0--172.16.00001101.0
172.16.14.0--172.16.00001110.0
172.16.15.0--172.16.00001111.0
Network components: --172.16.00001100.0--172.16.12.0
Mask parts: --255.255.11111100.0--255.255.252.0
After routing summary is: 172.16.12.0/22
eg：
sys
interface g0/0/1
rip summary-address 172.16.12.0 255.255.252.0
undo rip summary-address 172.16.12.0 255.255.252.0 - cancel route summarization
Four, RIPV2 certification
RIPV2 malicious authentication is a method of filtering the routing information;
Authentication Type: plain text authentication and MD5 authentication;
Certification is an interface going to do ;
Note: When configuring authentication of both interfaces are configured with the same authentication , or can not learn routes.
A configuration method - plain text authentication :
sys
interface g0/0/0
Simple cipher-authentication MODE RIP HUAWEI - plaintext configuration
Authentication information will be displayed at the time of the capture of the interface, as follows:
Configuration Method Two --MD5 Certification :
sys
interface g0/0/1
MD5 authentication-MODE usual RIP HUAWEI cipher --md5 configure
Five, RIP suppress the interface :
RIP does not send messages, but you can receive RIP packets;
silent-interface command to suppress the interface, so that it only receives the RIP packet, updates its own routing table, but does not send RIP packets;
Configured in RIP.
Configuration :
eg: configure interfaces on the suppression of 0 AR2, AR1 AR2 will not receive the RIP packets.
sys
rip
G0-interface Silent / 0/0 - 0 configuration to suppress the interface
Six, RIP version compatible configuration
The default between RIPv1 and RIPv2 are not compatible;
Setting an interface compatible with other routes .
experiment:
AR3 is version V2, which is a modification 1;
Open the debug mode on AR2 (AR2 is on RIPv2 version), you can view the output of debugging information:
Off debug mode:
Configuration :
AR2 enter a route, a modified version of RIP 1, other default unchanged:
sys
interface g0/0/1
rip version 1
dis rip 1 int g0/0/1
