Note

Enable Flowspec on BGP Side

You must enable the address family for propagating the BGP flowspec policy on both the Client and Server
using the following steps:
SUMMARY STEPS
1. configure
2. router bgp as-number
3. address-family { ipv4 | vpnv4 } flowspec
4. exit
5. neighbor ip-address
6. remote-as as-number
7. address-family { ipv4 } flowspec
DETAILED STEPS
Command or Action
Step 1

Step 3 address-family { ipv4 | vpnv4 } flowspec
Example:
RP/0/RSP0/CPU0:router(config-bgp)#
address-family ipv4 flowspec
Step 4
exit
Example:
