VPC Gateway Redundancy with the CSR 1000v
tested vPC Gateway Redundancy feature but struggeled a bit ->
!event manager environment RTB rtb-824519ebevent manager environment ENI eni-fa13f087event manager environment CIDR 0.0.0.0/0event manager environment REGION eu-central/192.168.0.2event manager applet replace-route2 event syslog pattern "\(Tunnel0\) is down: BFD peer down notified" action 1.0 syslog msg "Will now change route" action 2.0 publish-event sub-system 55 type 55 arg1 "$RTB" arg2 "$CIDR" arg3 "$ENI" arg4 "$REGION"!
I tested it in Frankfurt with a 192.168.0.0/16 vPC
The CSR had the IAM Role to "ChangeRoute"

Hi, Sorry didn't see this question earlier.
Most likely you are hitting the bug CSCuy96961.
Here is the workaround:
Add the following eem to both CSR configuration and reboot the router. This should be fixed in IOS-XE 16.3.
event manager applet restart-csrmgmt description "disable/enable csr_mgmt after Gi1 gets DHCP IP address" event syslog pattern "%DHCP-6-ADDRESS_ASSIGN: Interface GigabitEthernet1" action 1.0 syslog msg "%dCloud-vPodGW: Starting eem restart-csrmgmt" action 1.1 cli command "enable" action 1.2 cli command "config terminal" action 1.3 cli command "virtual-service csr_mgmt" action 1.4 cli command "no activate" action 1.5 syslog msg "%dCloud-vPodGW: Disabled csr_mgmt and waiting for 10 seconds" action 1.6 wait 10 action 1.7 cli command "activate" action 1.8 syslog msg "%dCloud-vPodGW: Enabled csr_mgt and exiting eem restart-csrmgmt" action 1.9 cli command "end"
