Hi,<\/p>\n

Small howto for people who are interested in making policy-based routing feature on Catalyst 3560.
\nFor example you need to use 2 different default routes for various VLANs.
\nImagine you receive a default route via a dynamic routing protocol (BGP, OSPF, \u2026).
\nYou need for VLAN ID 10 to take another default route for a specific reason.
\nYou create another default route via a static like this:<\/p>\n

ip route 0.0.0.0 0.0.0.0 outside_iface next_hop_ip 254<\/code><\/p>\n

With that, this second default route will never be used because the first has a better metric.
\n=> the need to use PBR\u00a0\";-)\"<\/p>\n

First, you need to activate this feature by changing a setting in the global configuration:<\/p>\n

sdm prefer routing<\/code><\/p>\n

This command allows to use the PBR feature on a Cisco Catalyst 3560 series which is by default not available.
\nYou have 4 modes:<\/p>\n
