General Routing

  • When 40G and 100G xcvrs are used together on the 16x100G PIC of QFX5700 such that they are connected to the same Broadcom Serdes Core on the PFE side, then one or more of the links from these interfaces might not come up. With this PIC, ports 0-3, 4-7, 8-11 and 12-15 share one Broadcom Serdes Core each.PR1867341

  • The order of precedence for a dot1p pointer for remarking is as follows:

    1. EFP

    2. Egress VLAN translation

    3. Outgoing interface

    PR1885513

  • On QFX5240, if egress mirroring is done on the egress interface of IFA Initiator node carrying [IFA + regular data] packets, only regular data packets will get mirrored as True Egress Mirroring is not supported on any of the Junos OS Evolved based QFX5000 platforms. PR1904230

Routing Protocols

  • With IGMP Snooping in EVPNoVXLAN with Mrouter sync feature enabled with "clear bgp neighbor all" in router where the igmp query is learnt locally when this AE goes from up to down state and all its mrouter states are removed and then the AE comes up [after core isolation] and the traffic coming into the system from another esi-lag will get dropped till all the query is learnt in AE and it becomes mrouter. This is the design limitation as it has core isolation in place and in this scenario we expect the traffic loss [12 sec] i.e till the time AE has learnt all the incoming queries from all vlan and marks its ifl as mrouter interface in corresponding VLAN.PR1876740
