Display Advertised-routes

OcNOS#show ip bgp rtfilter neighbors 12.1.1.1 advertised-routes
BGP RT-Filter table version is 1, local router ID is 20.1.1.2
Status codes: s suppressed, d damped, h history, a add-path, b back-up, * valid, > best, i - internal,
              l - labeled, S Stale, x-EVPN
Origin codes: i - IGP, e - EGP, ? - incomplete

 Example: The format 100:2:1:1 is interpreted as ORIGIN_AS:type/subtype:Route Target
          <Origin-AS>     : Autonomous System Number.
          <Type>          : The type/subtype of the extended community attribute.
                            (0-> 2-byte ASN, 1-> IPv4-address, 2-> 4-byte ASN)
          <RT-Identifier> : Route Target itself.

Here is the explanation of the show output fields.

Table 41. Description of the output field for the `show ip bgp rtfilter neighbors` command.
Field	Description
BGP RT-Filter table version	Version number of the RT-Filter table. Increments when changes occur.
local router ID	Router ID of the local BGP process. Example: 20.1.1.2
Status codes	Symbols indicating route status: `s (suppressed), d (damped), h (history), a (add-path), b (back-up), * (valid), > (best), i (internal), l (labeled), S (stale), x (EVPN)`.
Origin codes	Route origin information: `i (IGP), e (EGP), ? (incomplete)`.
Network	RT filter in the extended community format `<Origin-AS>:<Type>:<RT-Identifier>`. Example: 100:2:1:1 - Origin-AS=100, Type=2 (4-byte ASN), RT-Identifier=1.
Next Hop	IP address of the next hop for the route. For locally originated routes, this is `0.0.0.0`.
Metric	BGP metric for the route (if applicable).
LocPrf	Local preference value applied to the route.
Weight	Local router-specific weight attribute.
Path	AS path associated with the route.
Total number of route-targets	Displays the total count of RT entries advertised or received.
