Configuration Guide Configuring IP Addresses and Services
1.3.7 IP Source Route
Working Principle
Ruijie products support IP source routes. When a device receives an IP packet, it checks the options such as source route,
loose source route, and record route in the IP packet header. These options are detailed in RFC 791. If the device detects
that the packet enables one option, it responds; if the device detects an invalid option, it sends an ICMP parameter error
message to the source and then discards the packet.
After the IP source route is enabled, the source route option is added to an IP packet to test the throughput of a specific
network or help the packet bypasses the failed network. However, this may cause network attacks such as source address
spoofing and IP spoofing.

Configuring an IP Source Route
By default, the IP source route function is enabled.
The ip source-route command can be used to enable or disable the function.
1.3.8 IP Address Pool
Working Principle
A point-to-point interface can assign an IP address to the peer end through PPP negotiation. During PPP negotiation, the
server checks authentication information of the client. If the client passes the authentication, the server assigns an IP
address to the client (if the client is configured with an IP address and the IP address meets requirements of the server, the
server approves the IP address of the client). The IP address of the peer end can be directly specified or assigned from the
address pool.
Related Configuration
Enabling the Address Pool Function
By default, the address pool function is enabled.
The ip address-pool local command can be used to enable or disable the function.
Creating an Address Pool
By default, no IP address pool is configured.
The ip local pool command can be used to create or delete an address pool.
Assigning an IP Address to the Peer End through PPP Negotiation
By default, an interface does not assign an IP address to the peer end.
The peer default ip address command can be used to assign an IP address to the peer end.
