tl;dr;
[x] GRES should be enabled on all Juniper dual-RE devices
~~Because of Junos limitation with our current configuration, disable GRES from on dual-RE routers, see T191371~~
Test then re-enable GRES on:
```
cr1-eqiad
cr2-eqiad
cr1-eqsin
cr2-esams
```
[] Nonstop bridging should NOT be enabled on any devices (only useful for STP, which we don't use)
Remove from:
```
asw2-b-eqiad.mgmt.eqiad.wmnet
asw2-a-eqiad.mgmt.eqiad.wmnet
asw2-c-eqiad.mgmt.eqiad.wmnet
asw2-d-eqiad.mgmt.eqiad.wmnet
fasw-c-eqiad.mgmt.eqiad.wmnet
asw-b-codfw.mgmt.codfw.wmnet
asw-d-codfw.mgmt.codfw.wmnet
fasw-c-codfw.mgmt.codfw.wmnet
asw-c-codfw.mgmt.codfw.wmnet
asw-a-codfw.mgmt.codfw.wmnet
asw2-esams.mgmt.esams.wmnet
asw1-eqsin.mgmt.eqsin.wmnet
```
[ ] Nonstop active routing should be enabled on all switches with > 1 RE (handles LACP, BFD, OSPF, BGP, VRRP)
```
asw1-eqsin.mgmt.eqsin.wmnet
```
[x] Nonstop active routing should NOT be enabled on any router
[x] graceful-restart should be enabled on all devices where NSR is not configured (nonstop active routing and graceful-restart are mutually exclusive)
[ ] Write matching homer changes to make it systematic.
