Exemplary methods performed by a first network device (ND) 201 include generating first and second prefix entries associating incoming Internet Protocol (IP) traffic to first 208 and second 209 data structures (DSs), respectively. Generating the first DS includes generating a first proxy 215 including forwarding information causing incoming IP traffic to be forwarded to a second ND 202, and generating a second proxy 216 referencing a third DS 210. Generating the second DS includes generating a first proxy 218 including forwarding information causing incoming IP traffic to be forwarded to the second ND 202, and generating a second proxy 219 referencing the third DS 210. The methods include generating the third DS 210 including forwarding information causing the incoming IP traffic to be forwarded to a third ND 203, the third DS further including first state information 230 indicating whether the forwarding information included in the first proxies 215, 218 of the first and second DSs 208, 209 should be used for forwarding the incoming IP traffic. Network device 201 and network devices 203 and/or 204 can form an inter-chassis redundancy (ICR) system. For example, network device 201 can be configured as an active ICR device while network devices 203 and/or 204 can be configured as standby ICR device(s). In such a configuration, network device 201 is to forward incoming IP traffic to network device 202 while link aggregation LAG 260 is up (i.e., operational). In the event that LAG 260 is down (i.e., non-operational), the ICR devices switch roles, and network device 201 starts forwarding the incoming IP traffic to either network device 203 or 204, now operating as the active ICR device, which in turn will forward the traffic to network device 202 via LAGs 261 or 262, respectively. |
