Does an AR support multiple outbound interfaces

5

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.

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.

After an AR is configured with multiple outbound interfaces, the website cannot be accessed
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 dual uplinks in active and standby mode
An AR with dual WAN interfaces configured can support two uplink interfaces in active and standby mode. 1. Configure two static routes with different priorities. Generally, the data flow is sent out through the active link with a high priority. It is sent out through the backup link with a low priority only after a fault occurs on the active link. 2. Configure policy-based routing. Generally, the data flow is sent out through the active link through on policy-based routing. It is sent out through the standby link based on the default route in the routing table after a fault occurs on the active link.

Does an AR send and receive packets through different paths
An AR cannot send and receive packets through different paths, because packets sent from the AR can be controlled while packets received from carriers cannot be controlled.

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.
