Description
This example shows how to monitor BGP stats in a scenario with iBGP and dynamic neighbors.
Scenario
Step 1: Set the following configuration in DUT1 :
set interfaces dummy dum0 address 1.1.1.1/24 set interfaces ethernet eth0 address 10.10.0.200/24 set protocols bgp 20 peer-group overlay listen range 10.10.0.0/24 set protocols bgp 20 peer-group overlay remote-as 20 set protocols bgp 20 redistribute connected route-map REDIS set protocols route-map REDIS rule 1 action permit set protocols route-map REDIS rule 1 match interface dum0 set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 2: Set the following configuration in DUT0 :
set interfaces ethernet eth0 address 10.10.0.100/24 set protocols bgp 20 neighbor peer remote-address 10.10.0.200 set protocols bgp 20 neighbor peer remote-as 20 set service snmp community TEST set system login user admin authentication encrypted-password '$6$GSjsCj8gHLv$/VcqU6FLi6CT2Oxn0MJQ2C2tqnRDrYKNF8HIYWJp68nvXvPdFccDsT04.WtigUONbKYrgKg8d6rEs8PjljMkH0'
Step 3: Run command protocols bgp show ip summary at DUT0 and check if output contains the following tokens:
10.10.0.200Show output
IPv4 Unicast Summary (VRF default): BGP router identifier 10.10.0.100, local AS number 20 vrf-id 0 BGP table version 0 RIB entries 0, using 0 bytes of memory Peers 1, using 725 KiB of memory Neighbor LocalAddr V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State PfxRcd PfxSnt Desc 10.10.0.200 - 4 20 0 0 0 0 0 never Idle 0 0 N/A Total number of neighbors 1
Step 4: Run command protocols bgp show ip at DUT0 and check if output contains the following tokens:
1.1.1.0/24Show output
BGP table version is 1, local router ID is 10.10.0.100, vrf id 0 Default local pref 100, local AS 20 local address - Status codes: s suppressed, d damped, h history, * valid, > best, = multipath, i internal, r RIB-failure, S Stale, R Removed Nexthop codes: @NNN nexthop's vrf id, < announce-nh-self Origin codes: i - IGP, e - EGP, ? - incomplete RPKI validation codes: V valid, I invalid, N Not found Network Next Hop Metric LocPrf Weight Path *>i1.1.1.0/24 10.10.0.200 0 100 0 ? Displayed 1 routes and 1 total paths
Step 5: Run command protocols ip show route at DUT0 and check if output contains the following tokens:
1.1.1.0/24Show output
Codes: K - kernel route, C - connected, S - static, R - RIP, O - OSPF, I - IS-IS, B - BGP, E - EIGRP, N - NHRP, T - Table, v - VNC, V - VNC-Direct, A - Babel, F - PBR, f - OpenFabric, > - selected route, * - FIB route, q - queued, r - rejected, b - backup t - trapped, o - offload failure B>* 1.1.1.0/24 [200/0] via 10.10.0.200, eth0, weight 1, 00:00:01 C>* 10.10.0.0/24 is directly connected, eth0, 00:00:03
Step 6: Ping IP address 1.1.1.1 from DUT0:
admin@DUT0$ ping 1.1.1.1 count 1 size 56 timeout 1Show output
PING 1.1.1.1 (1.1.1.1) 56(84) bytes of data. 64 bytes from 1.1.1.1: icmp_seq=1 ttl=64 time=0.194 ms --- 1.1.1.1 ping statistics --- 1 packets transmitted, 1 received, 0% packet loss, time 0ms rtt min/avg/max/mdev = 0.194/0.194/0.194/0.000 ms
Step 7: Run command service snmp walk local-agent v1 TEST oid 1.3.6.1.2.1.15 at DUT0 and check if output matches the following regular expressions:
