有类路由:
有类路由不导入子网掩码。并且在路由更新后也提供了子网掩码。在有类路由中,子网掩码始终相同,并非所有设备都不同,我们可以在给定的图片中看到它。在有类路由中,不支持 VLMS(可变长度子网掩码)和 CIDR(无类域间路由)。
无类路由:
无类路由导入子网掩码,并在此使用触发更新。在无类别路由中,支持 VLMS(可变长度子网掩码)和 CIDR(无类别域间路由)。在无类路由中,hello 消息用于检查状态。在无类路由中,子网掩码始终不相同,可能因设备而异,我们可以在给定的图片中看到。
让我们看看有类路由和无类路由的区别:
S.NO | Classful Routing | Classless Routing |
---|---|---|
1. | In classful routing, VLMS(Variable Length Subnet Mask) is not supported. | While in classless routing, VLMS(Variable Length Subnet Mask) is supported. |
2. | Classful routing requires more bandwidth. | While it requires less bandwidth. |
3. | In classful routing, hello messages are not used. | While in classless routing, hello messages are used. |
4. | Classful routing does not import subnet mask. | Whereas it imports subnet mask. |
5. | In classful routing, address is divided into three parts which are: Network, Subnet and Host. | While in classless routing, address is divided into two parts which are: Subnet and Host. |
6. | In classful routing, regular or periodic updates are used. | Whereas in this, triggered updates are used. |
7. | In classful routing, CIDR(Classless Inter-Domain Routing) is not supported. | While in classless routing, CIDR(Classless Inter-Domain Routing) is supported. |
8. | In classful routing, subnets are not displayed in other major subnet. | While in classless routing, subnets are displayed in other major subnet.. |
9. | In classful routing, fault can be detected easily. | While in classless routing, fault detection is little tough. |
