Juniper EX系列交换机配置三层路由协议操作

静态路由协议

?手工添加到路由表

?下一跳必须有效

?所以的配置在 routing-options ?级别

Syntax：

[edit]

routing-options {

????static {

????????defaults {

static-options;

????????}

????????route destination-prefix?{

????????????next-hop next-hop;

????????????qualified-next-hop address?{

????????????????metric metric;

????????????????preference preference;

????????????}

static-options;

????????}

????}

}

Example:

[edit]

user@host# show

routing-options {

????static {

????????route 0.0.0.0/0 next-hop 192.168.0.1;

????}

}

???????RIP配置

— 最小 RIP 配置：

[edit protocol]

???protocols {

rip {

group group-name {

neighbor?interface-name;

}

}

}

— RIP ?重发布和 Export 策略

policy-options {

????policy-statement statics-to-rip {

????????from protocol static;

????????????????then accept;

????????}

}

— 应用策略的邻居

protocols {

????????rip {

????????group rip-neighbors {

????????????????????????export statics-to-rip;

????????????neighbor fe-0/0/0.0;

????????????neighbor fe-0/0/1.0;

????????????????}

????????}

}

查看RIP路由表

user@Riesling> show route protocol rip

inet.0: 27 destinations, 27 routes (27 active, 0 holddown, 0 hidden)

+ = Active Route, - = Last Active, * = Both

172.16.2.0/24 ?????*[RIP/100] 00:07:25, metric 2

????????????????????> to 172.16.1.2 via fe-0/0/0.0

192.168.8.1/32 ????*[RIP/100] 00:07:25, metric 2

????????????????????> to 172.16.1.2 via fe-0/0/0.0

192.168.24.1/32 ???*[RIP/100] 00:00:25, metric 3

????????????????????> to 172.16.1.2 via fe-0/0/0.0

???????Open Shortest Path First (OSPF)

开放式最短路径优先协议是一种链路状态路由选择协议，它产生于 I P 网络，发展成用于单个自治系统来分发路由选择信息。

单区域

[edit]

user@host# set protocols ospf area 0 interface ge-0/0/0

[edit]

user@host# show protocols?ospf

ospf {

????area 0.0.0.0 {

????????interface ge-0/0/0.0;

????????}

}

配置 OSPF 多区域

[edit]

user@host# show protocols ospf ?

ospf {

????area 0.0.0.0 {

????????interface ge-0/0/0.0;

????????}

}

[edit]

user@host# set protocols ospf area 1 interface at-0/1/1.100 ?

[edit]

user@host# show protocols ospf ?

ospf {

????area 0.0.0.0 {

????????interface ge-0/0/0.0;

????????}

????area 0.0.0.1 {

????????interface at-0/1/1.100;

????????}

配置 a Stub Area

[edit protocols ospf area area-id?]

stub <default-metric metric> <(no-summaries | summaries)>;

配置 a Not-So-Stubby Area

[edit protocols ospf area area-id?]

nssa {

area-range network/mask-length?<restrict>;

default-lsa {

default-metric metric;

metric-type type;

type-7;

}

(no-summaries | summaries);

}

配置 OSPF Virtual Link

当网络直接超过3 area，使用virtual Link 连接防止环路。

[edit protocols ospf area 0.0.0.0]

virtual-link neighbor-id router-id?transit-area area-id;

配置 OSPF Router Interfaces

d Configuring an Interface on a Broadcast or Point-to-Point Network

[edit protocols ospf area area-id?]

interface interface-name;

d Configuring an Interface on a Point-to-Multipoint Network

[edit protocols ospf area 0.0.0.0]

interface interface-name?{

neighbor address;

}

d Configuring an Interface on a Nonbroadcast, Multiaccess Network

[edit protocols ospf area 0]

interface interface-name?{

interface-type nbma;

neighbor address?<eligible>;

poll-interval seconds;

}

配置验证

可以使simple和MD5

[edit protocols ospf area area-id?]

authentication-type authentication;

[edit protocols ospf area area-id?interface interface-name]

authentication {

md5 key-id?{

key [ key-values?];

}

simple-password key-id;

}
