Sometimes it is required to test traffic through an alternative path before committing to it and allows for testing and monitoring of a specific application. So, in VOSS it is possible to create an ACL which can redirect source and destination traffic to a next-hop which overrides the routes in the GRT.
Below is an example filter which I tested using a VSP VM in GNS3 that redirects traffic with a source IP 10.10.10.10 towards a destination IP 18.104.22.168 with a next-hop of 22.214.171.124. Verified it works by using the statistics on the ACL and Wireshark on the outbound link in the topology.
filter acl 1 type inVlan
filter acl vlan 1 10
filter acl ace 1 100
filter acl ace action 1 100 permit redirect-next-hop 126.96.36.199
filter acl ace action 1 100 permit count
filter acl ace ethernet 1 100 ether-type eq ip
filter acl ace ip 1 100 src-ip eq 10.10.10.10
filter acl ace ip 1 100 dst-ip eq 188.8.131.52
filter acl ace 1 100 enable
