Hey! I am trying to setup a Juniper QFX5100 as a VTEP with a very classic setup. Everything works as expected, but the setup is only using one possible path from the underlay network.
I have the route to the other VTEP like this: # run show route 10.16.39.3 inet.0: 240 destinations, 1808 routes (240 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both 10.16.39.3/32 *[BGP/140] 00:38:24, localpref 500, from 10.64.0.5 AS path: I, validation-state: unverified to 10.64.0.23 via xe-0/0/46.181 > to 10.64.128.23 via xe-0/0/47.183 [BGP/140] 00:38:24, localpref 500, from 10.64.128.6 AS path: I, validation-state: unverified > to 10.64.128.23 via xe-0/0/47.183 [BGP/140] 00:38:24, localpref 500, from 10.64.0.3 AS path: I, validation-state: unverified > to 10.64.0.23 via xe-0/0/46.181 :vxlan.inet.0: 17 destinations, 21 routes (17 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both 10.16.39.3/32 *[Static/1] 00:31:10, metric2 0 > to 10.64.128.23 via xe-0/0/47.183 So, from an IP point of view, I have two available routes to the other VTEP. In the :vxlan.inet.0 table, only one route is kept. I suppose the problem is at this point. Looking at the forwarding table, I have only one indirect next-hop too: # show route forwarding-table family ethernet-switching bridge-domain vlan-client1-543 extensive Routing table: default-switch.bridge [Index 4] Bridging domain: vlan-client1-543.bridge [Index 3] VPLS: Enabled protocols: Bridging, ACKed by all peers, [...] Destination: 0a:e3:40:00:00:d9/48 Learn VLAN: 0 Route type: user Route reference: 0 Route interface-index: 575 Multicast RPF nh index: 0 P2mpidx: 0 IFL generation: 142 Epoch: 0 Sequence Number: 0 Learn Mask: 0x4000000000000000000000000000000000000000 L2 Flags: control_dyn Flags: sent to PFE Next-hop type: composite Index: 2045 Reference: 6 Next-hop type: indirect Index: 131317 Reference: 3 Nexthop: 10.64.128.23 Next-hop type: unicast Index: 1928 Reference: 4 Next-hop interface: xe-0/0/47.183 So, how to ensure the two possible next-hops are copied to the ":vxlan.inet.0" table? -- Make input easy to prepare and output self-explanatory. - The Elements of Programming Style (Kernighan & Plauger) _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
