1. Set up a policy to redistribute the routes
[edit]
#set policy-options policy-statement name-of-policy from protocol ospf
#set policy-options policy-statement name-of-policy then accept

2. Apply the policy :
[edit]
#Set protocols bgp export name-of-policy

This will look like:

policy-options {
        policy-statement ospf-to-bgp {
                from protocol ospf;
                then accept;

protocol {
        bgp {

                export ospf-to-bgp;

Subject: [j-nsp] BGP-OSPF route redistribution

Hi,

I'm new to Juniper routers, so please forgive me if this is a FAQ (I
couldn't find anything in the digest):

I'm trying to set up an M40 to redistribute routes from OSPF to BGP,
exchanging with a Cisco 7507. The M40 sees the routes from the Cisco just
fine, but the Cisco doesn't receive anything. Is there anything I need
to do to emulate the Cisco "redistribute ospf <...>" statement?

The relevant bits of the configs are below. Thanks in advance for any
help!
