After an AR is configured with multiple outbound interfaces, the website cannot be accessed

1

This condition generally occurs on the networking of equal-cost static route with two outbound interfaces.
- In V200R003, the web page cannot be opened when online banking services with high security requirements are accessed.
- In V200R005 and later versions, run the ip load-balance hash { src-ip | dst-ip | src-dst-ip } command to solve the problem that packets sent and received through different paths.

Does an AR support multiple outbound interfaces
Multiple outbound interfaces of AR routers are configured as follows: 1. The AR150 series routers support dual WAN access. Some AR models provide two electrical interfaces as WAN interfaces, while other models provide only one electrical interface as the WAN interface. To implement dual WAN access, LAN interface FE0 must be used as a Layer 3 interface. - Types of WAN interfaces: AR151, AR151W-P, AR151G-HSPA+7, and AR151G-C: FE electrical interface AR156 and AR156W: ADSL-B/J interface AR157, AR157W, AR157VW, and AR157G-HSPA+7: ADSL-A/M interface AR158E and AR158EVW: G.SHDSL Interface - LAN interface FE0 can be used as a WAN interface. 2. The AR160 series routers support dual WAN access. - Types of WAN interfaces: AR162F: SA interface AR168F: G.SHDSL interface AR169F, AR169FVW, and AR169FGVW-L: VDSL2 interface The AR160 series has a GE combo interface functioning as a WAN interface. - LAN interface GE0 can be used as a WAN interface. 3. The AR200 series routers support dual WAN access. - Types of WAN interfaces: AR201 and AR201VW-P: FE electrical interface AR206: ADSL-B/J interface AR207, AR207V, AR207VW, AR207V-P, and AR207G-HSPA+7: ADSL-A/M interface AR208E: G.SHDSL interface - LAN interface FE0 can be used as a WAN interface. 4. The AR1200 series routers support dual WAN access even without an expansion card installed. 5. The AR2200 series routers support dual WAN access on fixed interfaces. 6. The AR3200 series routers support dual WAN interfaces.

Method of configuring interface policy routing of an AR router
The roadmap of configuring interface policy routing of an AR router is as follows: 1. Configure a traffic classifier. 2. Configure a traffic behavior (redirection to a next hop or an outbound interface). 3. Configure a traffic policy. 4. Apply the traffic policy to the interface in the inbound direction. Supposed that the intranet is composed of two network segments 1.0 and 2.0, and traffic transmitted over 1.0 is redirected to China Telecom and traffic transmitted over 2.0 is redirected to China Unicom, then the configuration is as follows: # acl number 3001 rule 5 permit ip source 10.1.1.0 0.0.0.255 acl number 3002 rule 5 permit ip source 10.1.2.0 0.0.0.255 # traffic classifier redirect-dx operator or if-match acl 3001 traffic classifier redirect-lt operator or if-match acl 3002 # traffic behavior redirect-dx redirect ip-nexthop 1.1.1.1 traffic behavior redirect-lt redirect ip-nexthop 2.2.2.2 # traffic policy celvluyou classifier redirect-dx behavior redirect-dx classifier redirect-lt behavior redirect-lt # interface GigabitEthernet0/0/1 traffic-policy celvluyou inbound # For details about specific configuration cases, see the URL: Example for Configuring Interface PBR.

STAs cannot access some websites
Procedure for troubleshooting this problem 1. Access other websites on the STA. 2. Try to access the websites through the wired network. If these websites cannot be accessed through both wired and wireless networks, this problem is not related to the AC or AP. In this case, check the websites and egress devices.

Does an AR support two uplink interfaces in load balancing mode
If an AR has two WAN interfaces configured, the two uplink interfaces work in load balancing mode. 1. Configure two equal-cost static routes. 2. Configure policy-based routing to change the forwarding path of packets.
