If an AR supports two outbound interfaces in active and standby mode, the external network cannot access the IP address of the interface on the standby link

1

An AR supports two outbound interfaces in active and standby mode. When the AR pings the IP address of the interface, it sends packets to the external network through the active link. However, it cannot be pinged because the source and destination IP addresses are different.

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.

Double outlet of AR routers active/standby backup, the external network is unable to access device interface address of the standby link.
Because do double outlet is the active/standby,When ping standby link interface address ,AR routers to extranet address returned packet is through the main link out of; as a result, the source and destination addresses were inconsistent, so ping doesn't make any sense.

For an AR with two outbound interfaces, NQA for static routes can be used to implement quick switchover from the active link to standby link
For an AR with two outbound interfaces, Network Quality Analysis (NQA) for static routes can be used to detect faults of active and standby links in order to implement active/standby link switchover when the active link fails. For the configuration example, see Example for Configuring NQA for IPv4 Static Routes.

Which types of active interfaces and standby interfaces are supported by the AR router
Types of active interfaces supported by the AR routers: Layer 3 Ethernet interfaces and their sub-interfaces, dialer interfaces, ATM interfaces, ISDN BRI interfaces, asynchronous interfaces, cellular interfaces, PON interfaces, MP-group interfaces, MFR interfaces, FR sub-interfaces, and serial interfaces and their sub-interfaces Types of standby interfaces supported by the AR routers: Layer 3 Ethernet interfaces and their sub-interfaces, dialer interfaces, ATM interfaces, BRI interfaces, asynchronous interfaces, cellular interfaces, MP-group interfaces, MFR interfaces, FR sub-interfaces, and serial interfaces and their sub-interfaces. ISDN BRI interfaces, PON interfaces, and asynchronous interfaces cannot be used as active or standby interfaces on AR120&AR150&AR160&AR200 series.

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.
