Example:
RP/0/RP0/CPU0:router(config)# prefix-set PERMANENT-NETWORK-IPv4
RP/0/RP0/CPU0:router(config-pfx)# 1.1.1.1/32,
RP/0/RP0/CPU0:router(config-pfx)# 2.2.2.2/32,
RP/0/RP0/CPU0:router(config-pfx)# 3.3.3.3/32
RP/0/RP0/CPU0:router(config-pfx)# end-set
Enters prefix set configuration mode and defines a prefix set for contiguous and non-contiguous set of bits.
Step 3
exit
Example:
RP/0/RP0/CPU0:router(config-pfx)# exit
Exits prefix set configuration mode and enters global configuration mode.
Step 4
route-policy route-policy-name
Example:
RP/0/RP0/CPU0:router(config)# route-policy POLICY-PERMANENT-NETWORK-IPv4
RP/0/RP0/CPU0:router(config-rpl)# if destination in PERMANENT-NETWORK-IPv4 then
RP/0/RP0/CPU0:router(config-rpl)# pass
RP/0/RP0/CPU0:router(config-rpl)# endif
Creates a route policy and enters route policy configuration mode, where you can define the route policy.
Step 5
end-policy
Example:
RP/0/RP0/CPU0:router(config-rpl)# end-policy
Ends the definition of a route policy and exits route policy configuration mode.
Step 6
router bgp as-number
Example:
RP/0/RP0/CPU0:router(config)# router bgp 100
Specifies the autonomous system number and enters the BGP configuration mode.
Step 7
address-family { ipv4 | ipv6 } unicast
Example:
RP/0/RP0/CPU0:router(config-bgp)# address-family ipv4 unicast
Specifies either an IPv4 or IPv6 address family unicast and enters address family configuration submode.
